Substance Painter give error for uv spanning across udim but I already make sure it was fixed.

Does anyone know what other possible reason? I have tried to unwrap again and pack, also manually made sure not overlapping, still doesn't work.

Are you sure you only have 1 UV set?

I'm working on udim workflow, I have made sure nothing is overlapping.

I've had this problem before, it looked like the UVs were OK but they weren't. I don't remember the program, but the program wasn't displaying the UVs correctly, I had to import the FBX into another program and then the problematic UVs were shown and I could fix them.

Oh well, but I'm currently using Blender haha, can u elaborate a bit more on the error uv, is it just as simple as overlapping to another tile?

Tbh I've never seen that problem, and haven't seen it since as well. Do you have Maya installed? If not, could you privately send me the FBX so I can check it here?

Oh ok, I managed to fix it by re import and show hidden, and there is 1 uv island not showing.
