    @Hoodelali Thank you.

    Most of what I intend to post here is new content that covers broader concepts with more of an emphasis on the how and why behind it all. Some of this content will be very niche hard surface, mechanical and fabrication stuff and how that ties into creating art. There will also be some general art process stuff that I think is worth sharing. The more technical stuff will be very image heavy and I've been considering doing some of that content as video (maybe audio) but it really depends on how it all works out and what people are interested in. Organizing links back to the existing write-ups so it's easier for people to find and share what their interested in will be a part of this thread but it will be one of the smaller parts.

    Subdivision modeling: process optimization, order of operations and flat surface topology.

    Process optimization is an important part of skill building and taking the time to evaluate the underlying assumptions that drive your modeling strategy can help improve both the efficiency and quality of your modeling process.

    Below is a visual overview of a simple modeling task. Fill the cap between two cylinders that have different segment counts and add support loops to create a subdivision ready cage mesh. How much time and effort it takes to complete this simple task will depend on the modeling tools and strategies used.



    The following example is a modeling process that's driven by a lot of common preconceptions and assumptions. Here's a breakdown of the rational behind this process and a summary of how the model was created.

    Subdivision modeling implies that the cage mesh needs to be all quads with even grid topology to avoid smoothing artifacts. Starting with fixed topology suggest that everything needs to be manually joined together to create the perfect edge flow. Edge extrusion modeling extends the existing topology so it will be the fastest way to fill in the cap. Loop cut, fill and connect are basic operations that provide granular control of the topology layout phase of the process.

    Modeling process 1 (≈ 48-62 individual operations.)
    • Extrude upper outer diameter support loop.
    • Extrude upper inner diameter support loop.
    • Fill radial segment - 12x.
    • Cut lower outer diameter support loop.
    • Cut low inner diameter support loop.
    • Join inner diameter support loops as quads - 42x. (Alternate: select and fill as quads - 30x.)



    This modeling process relies heavily on a brutally straightforward approach that uses a very limited selection of modeling tools and a strategy that follows whatever trajectory feels right in the moment. There's a significant amount of time spent on repetitive modeling tasks and the misconception that everything MUST resolve into quads to be subdivision ready only compounds this problem. What follows is a look at whether or not the previous assumptions created artificial limitations that generated unnecessary complexity.

    Modeling process 1 technical parameters:

    All quad geometry - Unless there's a specific technical limitation that absolutely requires the cage mesh be all quad geometry there's generally minimal benefit to manually adjusting the topology to create it. Simply subdividing the cage mesh will make it all quads. If quad grid topology is required for other process (like detail sculpting) then using automatic quad re-meshing tools is a better approach. The assumption that all subdivision cage meshes need to be quad grids is something of a misconception and in this case it's an artificial limitation.

    Fixed segment counts - Part of the block out process is figuring out how much geometry will be needed for subsequent modeling operations. There will be situations where it's either impossible or impractical to plan for all additional details and in these situations the base geometry will become a limiting factor. This is a realistic technical limitation and it's important to build an understanding of how to work around issues caused by having a limited amount of geometry to work with.

    Manual topology routing - There are certain cases where manual topology routing is necessary but unless the automatic tools have failed to create usable topology there's no real benefit to manually creating all of the topology flow. Sometimes there's a tendency to assume that creating every face and placing every support loop by hand improves the quality of the mesh but reality is this is just needless busy work and this behavior should be avoided whenever possible.

    Edge extrusion modeling - Basic manual modeling tools can be used to accomplish a wide variety of tasks and tend to have a high degree of granular movement control but that doesn't mean they are always the best tools for the job. The biggest drawback to using these tools is it can be difficult and time consuming to maintain consistent edge width. More complex tools can be used to place support geometry and automatically maintain a consistent edge width. This will improve both the process efficiency and visual quality of the model. Improving the edge width consistency tends to improve the readability of the shapes and helps provide a clean, professional look.

    With the exception of fixed segment counts, most of these assumptions introduced artificial limitations that negatively influenced the modeling process by narrowing the tool selection and increasing the number of manual operations. If edge extrusion was the method of choice then it would be much better to extrude the inside and outside segments to form the support loops then fill the faces between them.



    The only really important part of the topology is the support loops on either side of the outer bounds of the main shapes. Flat areas are largely unaffected by changes in topology so it makes more sense to average out the the differences between the segments there rather than in the support loop around a key shape transition. With this broader context that's now backed up with experience gained through experimentation it becomes more obvious that the only real constraint here is the starting geometry. The rest of the process is open to interpretation.

    The following example is a modeling process that applies what was learned by removing unnecessary limitations, expanding the tool selection and adjusting the order of operations. Here's a breakdown of the rational behind this process and a summary of how the model was created.

    Modeling process 2 technical parameters:

    Fixed segment counts - In certain situations the underlying topology will be a limiting factor that determines how much geometry is available to work with. In these cases the fixed segment count of the inner and outer diameter is the only true limitations here.

    Abandoning the previously mentioned preconceptions means it's possible to explore new ways of approaching the problem of connecting two support loops with different segment counts. Thinking about what's actually important and what tools are available will help identify more efficient ways of adding the support loops around the shapes.

    Modeling process 2 (≈ 3-5 individual operations.)
    • Fill half cap - 2x.
    • Bevel / chamfer outer and inner diameter to add support loops.
    • Add edge between inner and outer support loops on the cap - 2x.

    Changing the order of operations and tools used means it's possible to add most of the support geometry in a single step and all of the newly added support loops will have a consistent width. The flat area between the two support loops around the inside of the cap is used to absorb any major topology changes without causing any major smoothing artifacts. Not only does this modeling process ensure that potential shading issues are minimized but there's also the added benefit of having a simplified mesh that's easier to work with.



    In most cases: the important topology layouts are around the shape boundaries and are made up of the support loops that hold the shapes. Whatever happens on the flat surfaces is often irrelevant. Trying to resolve all of the intersecting edge loops into quad geometry doesn't improve the smoothing results and (in this case) would only add unnecessary complexity.

    That's not to say that it's unimportant to be aware of how the underlying topology effects subdivision smoothing behavior or to just ignore technical specifications when situations call of quad grid topology. Instead the message is that, in most cases, a few triangles here and there is a moot point if they aren't causing any major subdivision smoothing artifacts. Along similar lines: N-gons can be especially useful since they make the mesh easier to work with and when used correctly they have virtually no downsides compared to mixed quad / triangle topology.

    The most important takeaway here is the most important geometry is the edges that define the shapes and the support loops that back up these shapes.

    Below is a sample of a variety of topology strategies that all produce similar results. Double looping isn't always necessary but it can be helpful on large flat surfaces where the distance between support loops is quite wide. It's also worth noting that there's practically no distinguishable difference between the all quad geometry and the mixed triangle topology when it's used on a flat surface. This isn't an exhaustive list of all the possible topology combinations but it illustrates the point.



    Recap:

    Taking time to evaluate the assumptions that drive the modeling process is an important part of skill building. Automatically following popular modeling mantras (without evaluating the broader context behind the how, when and why) can introduce unnecessary process restrictions that tend to lead to extra work and excessive complexity.

    Evaluate whether or not these assumptions introduce artificial limitations and experiment with different tools and order of operations to identify simpler and more efficient ways to model the underlying shapes.

    Great posts, Frank. :) Your last post reminds me that I need to embrace how subdivision is just an approximation and use more shortcuts to model faster. I've avoided Blender's bevel modifier like the plague since I obsess over perfectly straight support edges when, in hindsight, wobbly support edges aren't really noticeable after they're subdivided and especially after texturing.

    Are you using 3ds Max in your screenshots btw? I had to add a bevel weight to those bottom two diagonal edges connecting the cylinder to the cuboid in Blender since its bevel modifier doesn't support both sharp and arc outer miter types at the same time.

    Also, an important question: do you model the high poly base mesh and the low poly model at the same time in order to have most (like 80%~) of the low poly done right off the bat? I can see a significant advantage of using the bevel modifier instead of manual support edges in that there are much less support loops to remove for the low poly as opposed to using manual support loops.

    @Nominous Thank you, glad you enjoyed the content. Overall I'd have to agree that getting a clean and consistent result is (almost always) an important priority.

    Modifier based modeling strategies can be a really efficient way to work since the underlying mesh is kept relatively simple. This makes the model easier to edit since most of the support loops are generated by the modifier system and will remain editable (via modifier settings) throughout most of the modeling process.

    Offloading repetitive modeling tasks to tools and modifiers should reduce manual editing and increase shape consistency. The structure of the underlying mesh topology tends to have the single greatest influence over the quality of the geometry generated by modifiers and other tools. If the input mesh is clean, straight and well organized then the support loops added by the modifiers should be clean, straight and well organized.

    It should be possible to re-create the previous example without having to apply any modifiers. Here's an example that shows the base mesh and modifier settings required to get this to work in Blender 2.91. Depending on the shapes, angle based modifier controls aren't always accurate or reliable so sometimes it's necessary to use grouping or weights to achieve the desired results.


    Correct: there's a significant efficiency bonus to using the same base mesh for both the high poly and low poly models.

    Using modifiers to control the geometry density of specific features means this process works in both directions since the parameters can be used to add or remove geometry from across the entire mesh or specific areas.

    How complex this setup is depends entirely on the project and the complexity of each individual part. It's all about balancing shape accuracy and editability to efficiently arrive at a result that hits the project's quality goals.

    This process is something I plan on covering in the near future.

    Subdivision modeling: use more geometry or create better geometry?

    Removing subdivision smoothing errors from shape intersections on curved surfaces is a common theme for questions about hard surface subdivision modeling. A lot of these questions are about pinching and stretching issues near corners and around shape transitions. Most of these questions have been asked countless times and more often then not have been answered with some variation of "Just use more geometry." but is this really the best answer?

    More importantly, if using more geometry is the best answer to these questions then how much more geometry is enough geometry?

    In most cases: increasing the geometry density does tend to increase the overall accuracy of the underlying shapes but it also tends to increase the complexity of the base mesh. Adding unnecessary complexity will make it harder to edit the base mesh and using too much geometry on a small segment of the model can generate it's own type of smoothing artifacts.

    Outside of the obvious cases where there isn't enough starting geometry to support the intersecting shapes, arbitrarily increasing the number of segments in the starting geometry can be a viable solution to remove some smoothing issues but there's diminishing returns on the trade off between accuracy and efficiency.

    In some cases there's already more than enough starting geometry and the smoothing issues are caused by improper geometry distribution or topology flow that disrupts the natural forms of the underlying shapes. Fundamentally these type of smoothing issues are problems with the underlying shapes not the geometry density. Blindly increasing the amount of the geometry will work but it's a brute force approach that doesn't address the root cause of the issue.

    Subdivision modeling is a [mostly] approximate process but the smoothing behavior is relatively consistent across all platforms. To understand how subdivision smoothing works it's important to break things down into their simplest forms and observe the fundamental smoothing behavior of the basic shapes. Once subdivision smoothing behavior is understood it becomes easier to plan out efficient topology routing solutions for complex shape intersections.

    Below is an example of basic cylinder geometry:

    Row 1: The edges that define the cylinder wall segments tend to pull inwards uniformly. To counter this it's necessary to add support loops around the edge loop at the top and bottom of the cylinder. These support loops counter the uniform inward pull and deform the top of the shape into a flat plane with a rounded transition into the cylinder wall.

    Row 2: Moving an individual segment of the cylinder wall (in or out, up or down, right or left) will change the spacing between the segments and this causes the wall of the cylinder to deform. Failure to maintain concentricity and spacing of cylinder wall segments is a major cause of smoothing artifacts on curved surfaces.

    Row 3: Adding edge loops that run perpendicular to the cylinder wall segments has virtually no effect on the curvature of the cylinder wall. Placing additional edge segments between existing cylinder wall segments tends to disrupt the subdivision smoothing which flattens the cylinder wall. Adding support loops to either side of existing cylinder wall segments tends to disrupt the subdivision smoothing and causes pinching.

    As shown in this example: moving existing cylinder wall segments can cause undesirable deformation. Additional geometry that runs perpendicular to simple curves tends to have a relatively minor impact on smoothing behavior along the curve. Additional geometry that runs parallel to existing edge segments in the cylinder wall tends to disrupt the smoothing behavior and is a major cause of smoothing artifacts on curved surfaces.

    To avoid these kind of smoothing errors it's important to maintain a relatively consistent spacing between curve segments and ensure that the smoothed mesh components and surface features are concentric to the wall of primary shape.



    Below is an example of basic rectangle geometry:

    Row 1: The edges that define the volume of the rectangle tend to pull inwards uniformly. To counter this it's necessary to add support loops around the edges that define each face of the rectangle. These support loops counter the uniform inward pull of the smoothing and deform the basic shape into a series of flat surfaces with a slightly rounded transition between each surface.

    Row 2: Adding geometry to or moving geometry along flat surfaces [between the outer support loops] generally has no major impact on the overall shape. Moving surface geometry components out of plane does cause deformation.

    When properly supported, flat surfaces are generally very tolerant to substantial topology changes so they can be a good place to simplify the mesh by culling unnecessary edge loop propagation. Flat surfaces that are angled, relative to other surfaces, should be flat to themselves. Keeping shape boundaries well supported and individual surface coplanar should be all that's required to prevent major smoothing issues on shapes with flat surfaces.



    The previous observations seem fairly obvious but it's important to keep this information in mind when merging shapes. Trying to add geometry to curved surfaces, without accounting for the effects of edge loop propagation, often results in pinching and stretching errors.

    The modeling process shown below seems to work but once the final support loops are added to the cube they run off the cube and parallel the existing geometry of the cylinder. This changes the segment spacing in that area and causes undesired cylinder wall deformation.



    Moving the extra edge loop along the cylinder wall can reduce the severity of the smoothing artifacts but it generally doesn't fully resolve the issue. It is possible to manually re-adjust the segments so things are relatively smooth but this often requires a significant time investment and tends to introduce other issues with the overall accuracy of the major shapes.

    When asking for feedback on resolving this type of smoothing error, it's very common to get a vague answer like "Just add more geometry." and that's understandable, because this strategy is simple, easy to explain and generally works. Sadly this advice is often simplified into something along the lines of "Just double or triple the segment count." Most of the time this will work but it's not an optimal strategy and this kind of advice ignores the wider context of what's appropriate for a particular part of a model.

    Arbitrarily increasing the complexity of the model without addressing the root problem that's causing the smoothing error is a sure fire way to reduce process efficiency. It will also make it more difficult for anyone who has to come back and make adjustments to that part of the model. This is why it's important to evaluate what's actually causing the smoothing error and take other factors (such as object size, average view distance, complexity of adjacent mesh segments, etc) and make an informed decision about where to add the additional geometry.

    A better answer is: match the segments of the intersecting shapes and use the appropriate amount of geometry to match the necessary edge loops on the adjacent shapes.

    Below is an example of how the number of segments on the larger cylinder can be increased to match the number of edges that make up the intersecting rectangle. As discussed previously, the number and position of the segments in the cylinder wall are critical elements that influence smoothing behavior. It's also generally considered best practice to use the existing geometry as support for the shape transition area around the shape intersection.



    The process of segment matching is fairly straightforward and this is one of the reasons why it's important to block out all of the major shapes before investing a significant amount of time in adding support loops and other details. Establishing accurate shapes with good topology flow between them will make it easier to place and route support loops that won't cause major smoothing issues.

    With subdivision modeling: the goal should generally be to use the minimum amount of geometry required to effectively hold the required level of shape accuracy and surface details.

    Once all of this is understood and put into practice it becomes much easier to generate meshes that have a better balance between shape accuracy and process efficiency. Here's an example of the previous modeling process but the number of segments in the cylinder is increased slightly to match the number of segments required to support the intersecting cube.


    It's also important to view the mesh from multiple angles and evaluate the total prominence of any smoothing artifacts. A shiny preview material with a wide highlight roll off can really light up surface imperfections when a mesh is viewed from off axis glancing angles. Using this type of material and toggling the subdivision preview will help make it easier to identify the severity and source of any smoothing errors.

    When increasing the mesh density there's a definite fall off in quality as the amount of geometry increases and there's a corresponding jump in editing difficulties. This is why it's important to consider how visible a smoothing error is before investing a significant amount of time trying to remove it. If there's minor smoothing errors in a small segment of the mesh that's not regularly visible to players or if minor smoothing errors are covered by high frequency surface normal details then there's minimal benefit to achieving perfection in these areas.

    Below are three examples [with increasing mesh density] to compare how increasing the amount of geometry effects the overall visual quality of the subdivided mesh and editability of the base mesh.

    Here's the cube intersecting a 12 segment cylinder.



    Here's the cube intersecting a 24 segment cylinder.


    Here's the cube intersecting a 32 segment cylinder.



    As the density of the mesh increases there's a clear fall off in the rate of change at which the difference in visual quality is perceivable.

    This means that, past a certain point [for an object of a given size, viewed from an average view distance] increasing the number of segments in a cylinder will no longer have a measurable difference to what players experience. At this point there's very few reasons to continue adding additional segments.

    Where good enough is good enough will be different from project to project but there's a distinct case to made against over complicating the mesh. Time spent perfecting something that doesn't directly effect the playability or player's perception of the overall visual quality of the model is time that could be better used else where. This all circles back to why block outs are so important.

    Another point worth making is that there will be situations where it's either impractical, impossible or imprudent to increase the number of segments in the base geometry. Often there's cases where parts are very small or constrained by adjacent geometry and the cost of making minor improvements far outweighs leaving in minor smoothing artifacts.

    In situations like this it's best to try and reduce the visibility of minor smoothing artifacts by manually adjusting the mesh to help pull everything to shape when subdivision is applied. Often small, soft smoothing artifacts can be covered by surface noise in the normal textures.

    It's generally acceptable to make minor manual adjustments to small details constrained by adjacent topology but keep in mind that using this to make large changes to most of the shapes in an object can produce undesirable results. Excessive manipulation of geometry components to compensate for an issue caused by a lack of adjacent supporting geometry can generate it's own type of smoothing issues and tends to decrease the overall accuracy of the shapes.

    Below is an example of what this process can look like. Dissolve unnecessary edge loops and with subdivision preview enabled, scale or move the offending geometry components back into line until the stretching or pinching issues are minimized.



    The results are far from perfect but it is an improvement on the original base mesh's smoothing behavior. This strategy is really only useful on making minor improvements to parts that would have otherwise required reworking a large section of the mesh to blend in. Again, it's important to evaluate the root cause of the smoothing issues and address that whenever possible. This solution is only passable on minor parts that are generally out of the player's close view.



    All of these principles can be applied to other shapes. Below is an example of how this works with cylinder to cylinder intersections. Start by blocking out the major forms then match the number of segments in the intersecting shapes. Preserving the natural shape of the underlying geometry will reduce the likelihood of prominent smoothing artifacts.

    The mesh in this example is passable if the geometry density is constrained by adjacent shapes but it does have some deformation issues caused by the limited amount of geometry in the larger cylinder.



    Here's another example that shows the same modeling process with more starting geometry.

    The overall goal should be to preserve the natural forms of the underlying shapes and increasing the geometry density to closely match the segments of the intersecting geometry tends to improve both shape accuracy and smoothing behavior. Using the appropriate amount of geometry will help provide a good balance between shape accuracy and process efficiency.

    it's also worth noting that transitions areas around shape intersections can provide natural support loops that should be used to constrain any smoothing errors caused by any differences between the geometry of the intersecting shapes.


    Below are three examples to compare the difference made by increasing the geometry density of intersecting curve shapes.

    Here's the small cylinder intersecting a 12 segment cylinder.


    Here's the small cylinder intersecting a 24 segment cylinder.


    Here's the small cylinder intersecting a 32 segment cylinder.



    After a certain point it becomes necessary to also increase the number of segments in the smaller cylinder to match the segment increase in the larger cylinder. Failure to match the number of segments on curved intersections will generally just move the smoothing issues from one shape to the other.

    Intersecting shapes with flat segments and sharp corners tend to be more demanding than circular shapes with soft corners. This circles back to the idea that it's possible to adjust the underlying geometry to compensate for minor smoothing issues. With cylinder to cylinder intersections it's often possible to average out any minor smoothing issues over a wider area without needing to increase the density of the starting mesh.

    As shown in the example below: there is a minor decrease in overall shape accuracy but the tension in both curves helps pull everything back into shape. The accuracy penalty for making minor shape adjustments on this type of geometry tends to be much less than when it's used on intersecting shapes with strong linear features.


    Becoming proficient at subdivision modeling does require practice but it also requires learning to see the underlying shapes and being able to extrapolate new solutions from existing knowledge. Limited experience can be a barrier that makes it difficult to take relevant examples and apply them to new problems. The basic principles will work on most shapes. Start by learning the fundamentals and build up from there.

    Below are a couple examples that show how the topology for a through hole is essentially the same as the topology for a boss. The only difference is one pushes inwards and the other pokes outwards. There's very little magic. It's mostly about repetition and rhyme.


    There will be challenges along the way but it's important to keep going and to study how other artists have resolved similar problems. Sometimes it seems like it can't be that easy [because sometimes it's not] but it just take thoughtful practice and evaluation. Experimenting with different topology solutions and comparing the results can help identify winning modeling strategies.



    Here's another example: surely an oblong through hole must have different topology than what's needed for a circular through hole! Nope. It's pretty much the same, just split the circular through hole and fill the gap. Fundamentally it's mostly the same or variations on a theme because the underlying process (subdivision smoothing) is relatively consistent. It's all repeatable which is why it's important to research, experiment, evaluate and repeat.



    Below is another example that's a variation on the theme: does it need more geometry or does it just need better geometry?



    Well for starters it's overly complicated and poorly organized. But remember that there's cases where more geometry is a brute force solution to problems with the underlying shapes. Effective subdivision modeling is about using the minimum amount of geometry required to accurately hold the shapes.

    Here's an example of how a better result can be achieved with the same amount of starting geometry. Start by defining ALL of the basic shapes, use the existing geometry as support for shape intersections and place the intersecting geometry on or between existing segments as appropriate.



    Below is a comparison of the same shape with different mesh densities. Under optimal conditions there's very little practical difference between all of these. With that said, there will be certain situations where increasing the sharpness of the edge width by adding additional support loops will require more geometry to support the increased edge sharpness.

    Again it all comes down to what the project requires and knowing how and when to make tradeoffs between accuracy and efficiency. This is why it's important to block out everything beforehand and evaluate how accurate things need to be based on player view distance.



    How about this shape? More geometry or better geometry?



    Parallel edge propagation is making an absolute mesh of the underlying shapes. This is a case where increasing the geometry density will help and so will adjusting the placement of the cylinder's edge segments so the intersecting geometry is properly supported by the existing geometry.

    Here's one example of how these smoothing issues could be resolved without throwing a lot of geometry at the problem. Start by blocking out the shapes then match up the segments of the intersecting shapes. Try to preserve as much of the existing geometry as possible and use it as support for the shape intersections.

    The initial result is much cleaner than the previous version but it does have some unwanted deformation near the peak of the circle at the end of the slot. This minor imperfection can be resolved by shirking the height of the circle's center vertex at the surface of the curve.



    As before, increasing the geometry density does tend to increase the overall accuracy of the shapes. The question is how much has this increase improved the results and how much has it complicated the underlying mesh? The answer depends on the quality goals for the project.


    It's also worth noting that, when increasing the geometry, it doesn't always have to be an even number and the segments don't always have to align perfectly. it's very common for artists to stick with common even numbers like 8, 16, 32, 64 or 12, 24, 48, etc. All of these numbers are easy to work with and visualize but sometimes it's better to use less conventional numbers like 10, 14, 20, etc. Sometimes it's more important to line things up with the intersecting geometry than it is to have a common number of segments.
