Exporting polygroups to Maya correctly

ZBrush Usage Questions
#1

Hi everyone. I recently ran into trouble exporting polygroups from Zbrush 2018 to Maya 2018 correctly. If memory serves me right, before I could check Grp button in the Export Menu, then export an obj, and upon importing it into Maya I’d get the polygroups as separate meshes. If Grp was unchecked, I’d get all in one mesh.

Haven’t had to use this in a little while, but tried it today and ran into an issue that when Grp is turned on, the obj that’s exported is just lots of random separate groups of faces that have nothing to do with the polygroups I’ve setup within Zbrush.

Fbx and ma exports don’t export polygroups either, although fbx allows to create different material per polygroup so I could split them up by hand in Maya, however this is not ideal really…

Has anyone run into this? Is there any remedy? It’s not often that I need to exprot Polygroups as separate meshes, but would be good option to have. Thank you.

The FBX plugin will export polygroups as selection sets (“Export Polygroups as SSets” in the options). Or you could try GoZ which should send polygroups to Maya.

Hi Marcus, thanks a lot for the reply. The fbx does indeed create selection sets, however that still means having to go through manual splitting up in Maya. I will have a play with Goz today, couldn’t get it to work last night and had troubles with it in the past, objs being the most reliable for me. Shame they refuse to work as before now… :cry:

Why don’t you simply split the mesh in ZBrush first (Tool>SubTool>Split>Groups Split). You could then export as a single FBX file (make sure “All” is on at the top of the FBX interface).
