Why when I import model in Substance Designer my model is black and UV set is -1 ?

Hello!

I scanned the object, created the mesh, unwrapped it and texturized. In RealityCapture my object looks great!

I exported the model, opened in Substance 3D Designer and got fully black model. When I opened Substance baker settings it showed “UV set = -1”

Why is that happening and how can I fix it?
