For the UVs on negative coordinates, you'll have to modify it in order to be Substance Painter ready, yes.

 

For the overlapping UV islands, this is something game studios sometimes do for optimisation, but it surprised me a little bit on the scope.

With that being said, there is probably a logical explanation and I don't know how it supposed to loook in game.

 

I let you enclosed the mesh with the right coordinates, but I left the overlapping UVs untouched. You can try it this way, but I p

Hi @Maxwell29923943q5go,

 

Thanks for the message.

 

If you already have two maps ready made for this model, maybe the current UV Tile workflow isn't the good one for your project. Try to set the UV Tile to Convert UV Tiles into individual Texture Sets (Legacy) at the start of the project.

This way, you'll have two distinct Texture sets and the maps won't spill on each other. 

 

Let me know if this works for you.

Hmmm... Would you mind sharing the asset, so I can take a deeper look?

The error is due to the UVs. They have two main problems:

 

1. One UDIM has negative coordinates and unfortunately, Substance 3D Painter doesn't read UDIM in a negative space (below or on the left of tile 1001).

So make sure all the UVs are on a positive space before importing the Rifle.

2. Some UV islands are overlapping and this is definitely something you want to avoid.

This is probably what was causing the initial spilling.

Oh I see this is actually a asset from the ARK Devkit from ARK Survival Evolved, do I need to modify the file to be ready by substance painter ?
