Hi @Stromberg90, you need to import your asset with the "UDIM Tile" option to have access to the second UV space.


This does work, in it's current state I think this should be the default.
Now I haven't used UDIM's, but from what I understand and reading about it, the point is it gives you a texture per UV tile,
while what this does is wrapping which usually is the default behavior.
Fix at https://github.com/armory3d/armorpaint/commit/1225719ec19f5ba2a9cb8093704a11254400616f, thanks for report!
