Export issue with layers and normals

When I try to export my model with my textures it doesn’t work. I’ve tried every option but the textures and paintings don’t show up when I import it in Blender. GLB exported my painting layer but it messed up my topology… Isn’t there a way to export the textures as maps (roughness, metal, displacement, normal…) such as a displacement map like in ZBrush? What else can I do?

Thank you!
