weird dark spots on model

Irraka

As you can see I have these weird dark spots on my model and I don't know what's causing them. So what I did was bake the normals and ao in marmoset toolbag then combined the model in maya. Previewed the materials there again no issues then imported the model, normal and ao into substance painter and now im seeing these spots.









Here you can see what it looks like in marmoset toolbag. No issues.

Marmoset bakes to opengl by default, Substance defaults to directx when starting a project. any chance thats your issue?

Mesh is probably triangulated differently in toolbar from painter. 

Triangulate it properly and this goes away

I assume you bake in MikkT not Maya Tangent space right?
