Goz won’t transfer 3ds max materials Ids to polygroups in Zbrush. The model comes from max as an editable poly, with material ids and multi-material applied. In zbrush preferences import/export, import mat as groups is selected. After hitting the Goz button, it comes in Zbrush without any polygroup.
It works when I export the model as obj, with texture coordinates, export materials, and create mat-library selected from max. when I import the obj in Zbrush, polygroups are showing. When I send this imported obj from ZB to max with Goz, the polygroups turn to material ids as expected, but when I send it back to ZB the polygroups are lost.
Anyone have an idea what can go wrong ? thanks.
