3dsMax 2021.2 Smart Extrude

gandhics

New - Smart Extrude
Adjacent faces are completely rebuilt and stitched together, matching the final visual output.
No more need for time-consuming repairs on hidden faces or other geometric data resulting from extrusions.Selection Improvements
Loop and ring selection is now more intuitive at various component levels.
Hold Ctrl and click to add loops and limited loops.
Hold Alt and click to remove loops and limited loops.New - Spline Chamfer Modifier
Procedural chamfer on spline sd s modifier
Use Stack Selection, Limit Effect optionsNew - Bitmap Random Tiling OSL Map
Looks up a bitmap from UV coordinates and modifies each repetition so tiling is not evident. The shader has a mode to properly transform normal maps. It outputs the modified UV so it can be hooked up to other Bitmap Lookup shaders so you can apply the identical randomness, in addition, it outputs the Random Index itself to drive downstream synchronized modifications.New - PBR Mixer OSL Map
Mixes all parameters for two sets of PBR materials.New - 1 of N (filename) OSL Map
Picks one of the numerous inputs.New - Scale (color) / Scale (vector) OSL Map
Multiplies a color/vector by a floatNew - MultiMixer (color)/Mix (color) / Mix (vector) OSL Map
Mixes many pairs of color inputs driven by a single Mix input.New - Wireframe
Creates a wireframe with a fixed width relative to rendered pixels, with a square every 1x1 unit square in UV space.Random By Index(Color) OSL Map - New Randomize Per component optionCurve OSL Map - New UV input mode optionMultithreaded Push modifier - My persona test showing 1500% speed up.New - executeScriptFile() function for Maxscript.Improved Bake to Texture map list UI.Improved zoom extents behavior for perspective viewportsFaster loading scenes with many deep OSL shading trees.A warning is displayed when collecting more than 10 materials from the scene in SME.Render Message window - The Render message window has been redesigned to have a QT interface with a new color scheme, copy and paste is easier and you now have the option on whether to enable auto-scroll or not.Fixed a crash in a CAT Parent object when pressing the time warp button.Fixed the buttons to open Curve Editors for a CAT Layer displaying empty curve editors (no keys or curves).

With Blender 2.7x i used to use an add-on for this kind of extrusions, similar to Sketchup.

They are very handy. It's cool to see this kind of things in Max.

gnoop

Yeah, cool indeed.    And looks more reliable  than Blender one.    I use https://github.com/capnm/b8ExtrudePull  Works in 2.8   but  you have to clean redundant  edges and vertexes after it.

Im asking myself for 20 years why the extrude doesnt work like this. Great "we" have it now.

cptSwing

Nice. Between this, last cycle's FWN modifier, 3ds Max Indie ... slowly regaining some trust here.

That spline chamfer modifier looks nice too. I do get the impression development on data channel and mcg has stopped, though.

coven

I won't say anything about MCG at this moment. You could find out about things going on if you look at the roadmap or join beta. For DCM, we are still developing it. We added additional channels that it can digest recently with the edge weights and edge depth.

gandhics

This is me trying the feature. Try with Blender if you can do all of these.

Did I hear someone whisper "Bifrost" from the corner of the room? Have heard good things from the Maya people, don't really know what Bifrost encompasses really. I figured it was more of a focused houdini for liquids/fire etc.

And thanks for the reply!

coven

@gnoop it looks like when subtracting, they never go beyond an existing edge. Is there a reason for that?

Here is Smart Extrude in conjunction with working pivot.

As a user I really like this developer "battle" going on Cool stuff!

Bifrost is "just" visual programming. You can do everything with it form rigging to modeling to world building.
For now its only for FX, yes. Does take some more years until we see procedural modeling with Bifrost.

Did a little test yesterday. Just as an inspiration.

Yeah, it's not as cool as MAx one. Needs  a few extra clicks.

ZBrush also has something.. I think it's called QMesh or something? It looks pretty cool too.

gandhics

Also Blender one seems only extruding along normal. Max one can drag in any direction as long as you stay in the plane.

Cathodeus

Yes the max version is best. And react in expected manner. Couldn’t meet a case where is doesn’t work yet. (Except the tunnels but it is known). Congratulations 🍾

I wonder, will this replace the standard Extrude found in Editable Poly though? It's just pure weaksauce in comparison

coven

I think there are situations you would want the standard extrude, possibly. I'd be interested in what others think.

cptSwing

I figured it'd be left in for legacy purposes - I can't think of a situation where I'd need it over the new extrude to be honest

coven

We could certainly add it to the old extrude.

Cathodeus

@Martin I can see one case where it could be problematic. Low poly Modeling : Sometime in order  to reduce the amount off poly we can extrude a long poly from one side of an object to the other side while passing trough some other stuffs. In this case we don't want the algorithm to clip the interpenetration as it would be counter optimal [more geometry].

At least here in our pipeline [where we really push optimisations, level of details, etc ...].

Edited : Realised that the case isn't covered maybe 'yet'

Orphydian

As someone already suggested already a couple of ways to improve the already great smart extrude of Max the most popular is for the negative extrusion to produce holes instead of currently flipped polygons and bad geometry.

Noted.

Anyone interested in the Smart Extrude, we'd love to have you on beta.
