Working with Udims in maya, Substance painter, unreal and zbrush

ChrisTheArtist · Mar 2020

OK so I need immediate help with UDIMS in Maya to substance painter and possibly unreal engine but I'm having problems. First Substance painter isn't seeing the UDIMS properly in the 2D view and the naming of the texture sets didn't port correctly. I'm not sure if this is a Maya thing or a substance thing. I made sure when I put my FBX in substance painter that I turned on create texture set per udim. Below are picture of my process and files to see what I did wrong. Also could you provide a way you got around this and how did you do this in unreal engine

THe log throws a message saying you have polygons crossing over multiple UDIMs:

[Scene 3D] Errors have been found while splitting meshes per UDIM tile:
Mesh 'polySurface835' has a face spanning across multiple tiles (face tile 1, 1 with vertex at 1, 1.92958)

That's why it can't split your UDIMs properly. Make sure you don't have a vertex that would be right on the border of the tile.
