    @macaron10 Break the complex forms down into individual features then break those features down into radially tiling elements. Focus on generating accurate shapes first then use those shapes to guide the overall topology routing. After that just add the final support loops around the perimeter of the shapes and shape transitions.


    Here's some additional resources on creating radially tiling features and similar shapes:

    Trying to make this a hard corner


    My attempts:


    crease

    Should I just use booleans? The back faces are deleted

    Thanks

    just a very shoddy quick attempt but if you do not have a continuous loop down in that corner but an actual corner it will happen automagically
    not the exact same shape but you should get the idea

    Hey i am trying to model this ornamental design, im struggling with the circular section. Heres what ive got so far, i made the left and right side of the mesh seperatly after a failed attempt to make them in one mesh.

    Personally, I'd model a bunch of separate curly parts I can reuse and tweak, don't worry about overlaps, just kitbash them together. Either bake down all the details to a pretty simple mesh or use a tool like 3d coat that can voxelize the model. These types of details are pretty small and just become visual noise, so they don't need to be perfect.

    Hey, I am losing my mind over this shape. It doesn't help that I've already added a bunch of support loops. But I can't seem to get this shape without causing an unholy amount of pinching. I'd prefer to not run edge loops over the curve, even if I do, pinching is still present. Any help would be appreciated.

    What would be the most efficient way of modelling, or rather, remodelling an existing flat-ish modular piece (pic1) in blender to fit a corner shape like in the other pictures? The perfect case scenario is such that preserves UVs. The example in the images is not mine. My own attempt is the last pic. Ironically, it would be way easier to manually model it in sketchup simply because of its inference system.

    After you have insetted, extruded and scale your model to you liking you may rotate it 45 degree in the viewport and switching to orthogrphic view and then have a look into the bisect tool.. after pinning all UVs a simple edge selection and mkae face (with thr F2 addon) will also add correspondending UVs..  now this inclinded areas may need this inner setting and extrusion..

    Either you have to start with dense cylinders so you don't have to worry about topology and connecting edges or you would have to pay attention to cylinders sides to avoid triangles (which I think isn't a big issue in this case).

    Hi everyone! First post here on the forum :)
    Having a bit of a problem with this suppressor (trash panda by q), as I can't seem to make it keep the smooth curvature on the front side once I turn on the subd. By adding loops horizontally it also breaks the curvature, really got no clue what to do. Is it because I modeled around those 12 faces and the shape is not round enough? Thank you in advance for the help!

    Gotta be really careful when adding edge loops around a consistent smooth curve. Generally it's easiest to start with more geometry and you can terminate those extra edge loops in flat areas where it wont affect smoothing. I'd probably start with 36 or 72 loops around that cylinder.

  • takalamaonakara
    Hello there.
    I'm a total noob when it comes to 3d modeling and i've been wanting to make a paper art with some topography 3d models that i can get online. I tried using google and asking some friends, but I don't even know the correct terminologoy for this.
    So I'm gonna send 3 images that sparked my art idea as an example of what i want to do, from the starting 3d model, to the ending result.
    From the resulting 3d model (The low poly prisms) I'm gonna use pepakura designer to make a paper model.
    Can anyone help me on how to get from image 1 to 3????

    I guess any grid, elevated with for example a heightmap, splitted by faces, scaled by individual faces, extruded and maybe merged will do..



    Blender even does have a paper model exporter.. which may be a bad idea for this kind of model...

    Hi you've pretty much got it sussed, atm just lacking a bit of finesse. 

    Anyway here's a solution I'd shared when someone else was tackling a similar issue, on how to model ornamental shaped filigree - that might be useful including a couple of other workflow links as well:

    Either use the built in text tools or trace out the text, make sure it has thickness, use that to boolean into a beveled box, and you're done.

    it's a piece of soap that have embeded small bits in it , some are visible some are not , and some of them are just below the surface 

    what is the final product? a bar of soap in a (any really, iso, thirdperson, even firstperson) game?
    use a normalmap
     how close will you be getting to that soap that it needs to be modelled in? if its for advertisement, i would really just displace it.

    oh wait this is about the material/shader? i feel like this is totally the wrong thread for that.
    for games if you wanna go there, parallaxing could give a bit of a sense of pieces being inside and blurred away but i am not sure if it will ever be worth the efford.

    How would we get something like this in 3DS MAX? I found the Spring option in MAX but the vertical edges come out 'wonky' and are not perfectly in-line with eachother.  It also wouldn't let me just have faces only and insisted it give me an extrusion even if set to Zero depth(it would give me double-faces on top of eachother(so I would have to delete the thickness, adding more steps). Any help would be much appreciated.

    Could someone take a really quick look at this problem I've encountered please? It is about using instances and zeroing out orientations. I made a very quick YouTube video to show what is happening as I figured that would be easier. Thanks :)

    I have tried replicating what you did in the video but it works fine for me. Maybe try resetting the pivot point(press D and then right click drag menu) and then aligning the pivot to object. I'm sharing my attempt of replicating your issue, if nothing works maybe try deleting your maya pref folder in documents (make a backup before deleting.)

    Thanks very much for trying it out, I appreciate that. The difference is that I baked the pivot, so I could zero it out. It looks like your pivot isn't baked in your move settings. 
    When it isn't baked, there isn't a problem, but it means that it can't be zeroed. Thanks though, very kind of you.

    Good afternoon! first time posting here. I've acquired my computer last month and have been immensely enjoying the world of 3D ever since.

    [BLENDER]

    Currently learning materials. I wanted to model some lab equipment, and when making an erlenmeyer flask, thought of selecting the inner side polygons, duplicating, then separating. I capped the top of the object this created, but when I attempt to render, this object is acting weird. (Cycles, GPU (GTX1050, I don't have my glorious rtx 4080 at work)).

    For some reason, Projected shadow is pretty opaque. despite basically max transmission and subsurface, the shadows these project onto the flat surface below are opaque and dense when I expected a crystalline glass.

    What might I be overlooking?

    Thank you so much in advance. <3

    Hi, I'm not too clear on getting the proper shape transition. I'm sharing my attempts and problems I found, please have a look at them.I started of with quarter of 24 sides cylinder(6 sides) as I found easier to manipulate the overall shape but I was getting pinching or sharp edges. I believe I have to start with a higher polycount with the required curvature already established to avoid pinching or sharp edges but I'm not too keen on how to get the top transition detail with higher polys.

    I would like to see your methods and techniques to create this model.

    No problem at all. This model isn't for bake.
    Despite this, what do you think about the number of vertical loops? In my opinion, 72 loops for such cylinder is too much, but without them, the shading looks really ugly.

    I need something like this
    I am not satisfied with the effect, this "edge" it disappears too quickly, it should go all the way to the top.

    Yes I sometime use crease edge, but I look like it needs high subD lvl for very tight bevel, and works best with equal polygon size, maybe i am wrong. I still trying make good topology for this.

    Ohh well then.. maybe make it less disappearring, not using creased edges and also being satisfied with  this bulge like shape because glass bottles (flacons for perfume) are mostly not this sharp ? (Maybe very expensive onces.. which i couldn't afford :wink: )  I guess it's not in this close-up to se in the final scene ??.. but again.. it depends ..  :wink: ..  ..
