Hi there !

And, when I tried to bake it all in Substance Painter, I had weird artefact on my meshs :

I thought is was about the UVS, but I tried to export just one of the rocks from maya to bake it solo (without changing anything in the UVS or the substance bake settings, and it work perfectly :

So can you find why the bake is changing and do problems when i add others rocks ??

If you want a second pair of eyes, share the meshes (zip & attach to post).
