Gizmo Extrude New Polygroups

ZBrush Usage Questions
#1

Something that’s puzzled me for a while is why 2 of the extra functions of the Gizmo3D don’t work as described in the docs?

From the docs:

“For each new extrusion, a different PolyGroup will be applied to each of the extrusion’s sections. The extruded polygons also receive a dedicated PolyGroup. This is
so that you can later use PolyGroup operations like Tool >> Deformation >> Polish by
Groups”

So, no matter what, new polygroups are not created.

Also, the Ctrl+click scale to insert edgeloop doesn’t work either. It just scales or clips?

From the docs:

“While Gizmo 3D is active, holding the CTRL key and dragging the Gizmo 3D Scale
manipulator will create an edge loop along the boundary of the non-masked part of the
model.”

Thanks.

Hello @DannyMcGrath

I’m unaware if this is a bug, or simply an error in the documentation. If it is a bug, it’s a long standing one. I can’t remember transpose extrusion working that way in recent memory.

It is, however, similar to the way that ZModeler extrusion operations work. So if your mesh is of a low-ish polycount, you might opt to use that tool instead if you want auto-polygrouping.

In either case, if you would like an issue to receive technical attention in ZBrush, it must be reported to the developers via Pixologic Support.

Strange, because the docs are very specific(and exactly what you would need this feature for - polish by groups on a Dynamesh, for instance) and this goes back to a workflow that predates Zmodeler and the Gizmo3D - the docs for the Transpose Line extrude function state the same. I doubt it’s an error in the docs considering it’s so specific.

Also, Zmodeler is a completely different workflow for the purposes, but technically, new polygroup ring and leading faces on the Gizmo/Transpose extrude you would expect to behave the same as Zmodeler and receive new polygroups.

The only way to find out for sure and for the issue to receive technical attention if warranted, is to contact Pixologic Support as stated above.

Good luck!
