I go a model (subpatched parts mostly) that i exported to substance painter in order to paint it. After I exported it and painted it (got it in painter in low rez, non subpatched), i sent it back to LW, but i got stretchy looking texturing, as if the uv map was in linear whereas the model in subpatch. and even by switching the interpolation it does not solve the problem.
How do you work in this workflow?

Does i need to freeze the geometry before exporting?

Thanks
