Following the previous article on the new selection methods in 3ds Max 2021.2, we’ll now look at the Smart Extrude feature added in the latest release.

If you missed it, you can read here the previous article published in this series.

Keep in mind that for now this method only works if your geometry is an Editable Poly object. In addition for adjacent coplanar polygons, it will not work if you try to use it with an Edit Poly modifier.

It is fairly simple to try, SHIFT + Drag (Left Mouse Button) to Extrude inward or outward the selected faces. It is meant to be used with polygons and not with vertices or edges. The same shortcut works to create an Inset, with the difference that it’s done by using the Scale tool instead of the Move tool.

Like for the extrusion, the inset can be created inside or outside the selected faces.

As you can see from the video, once you apply a Chamfer modifier, it creates a clean geometry without any visible artifact.

  • Pros:
    • Fast extrusions
    • No need to clean up overlapping faces
    • Works relatively good with Chamfer modifier, does not create artifacts
  • Cons:
    • Only for Editable Poly
    • Does not keep quad topology

During some testing we had a few crashes using this new feature, mostly while creating multiple insets. The crash wasn’t of 3ds Max but of the entire computer so it may be something else; in any case make sure to save once in a while.

The next article in this series will be quite interesting as we’ll show you a cool way to remove texture repetition with the new Bitmap Random Tiling OSL map, but we’ll also present a sneak peek of a tool developed in-house, thanks to our efforts in the exciting world of R&D.

Remember the Endless Materials tool for Unreal Engine made by Roberto a few months ago? Well, it will now be available in 3ds Max as an OSL map to connect to your bitmaps.

Keep following us for more info.
