Hi all, I hope someone can help with this as I don't have a lot of time left to finish this asset up. Basically, long story short - I made an asset, UV'd it in Maya, textured it in Substance Painter, all looked great. Now I've imported the mesh into Unity and the UV's are stretched. This is the mesh in Unity - Mesh in Maya…
Oh my god, I actually love you so much! You've solved this for me. I'm an idiot and should have tried this. But even in the wireframe view in Unity I can see the Unity algorithm has triangulated it differently to the Painter export. Thank you so much!
