Metashape to Substance Painter with UDIMs

[wojtek]

Default export separates each UDIM tile into a separate Texture Sets, does anyone have any tips for this?

EDIT: If I Import/Export it through Zbrush it will load up properly in Painter. Something is off in how the .obj is formatted going out of Metashape it seems.

EDIT2: Depends how many Tiles there is so it's not a good solution.

EDIT3: I think something is broken and it may be related to this: https://www.agisoft.com/forum/index.php?topic=14860.0

I had this problem and found the solution in editing the obj with udims from metashape in c4D with arnold. (redshift will work as well probably). Then the obj will be imported in Painter correctly.

some new information;
metashape doesn't really export obj with udim, but the program exports mesh with submeshes. These submeshes get their own materials applied. Painter creates a texture set for each material.
My solution:
edit the obj and delete all lines with mtl  (like in newmtl) and save as a new .obj.
That you can import in painter and you get 1 texture set with a number of UV tiles.
Hope this helps

This is what I've been doing too but it will break after N amount of tiles too (9 I think).

@wojcek
I've tried it with 10 tiles and with 20 tiles, and I can get them opened perfectly, after editing the obj. I use metashape 1.8.5 and substance painter 8.3.0 build 2094 with "use UVtile workflow"checked.
