Hi there !

I made few rocks in maya and I decided to made one UV map for all of them

High & Low Poly :

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 ??

Hi! Judging from the screenshots, you use match by name and it doesn't give any matching errors. I wonder what the preview cage looks like?
If you want a second pair of eyes, share the meshes (zip & attach to post).

The problem was : I had multiples UV channels on two differents meshs and it was overlapping.
Thanks to Fabi_G to had find the solution !
