[Substance models] Improve how Basis are displayed. Aliasing on UV Seams. For many renderers, it's important that the normal vectors for all polygons point the same direction (usually from the inside of the mesh toward the outer surface); if they're inconsistent, you get errors like "invalid normals" or you might just get weird rendering results, depending on the software. This way you have a tangent space representation of your meshes that you can use for advanced rendering. It could maybe happen because of a faulty custom tangent space plugin.
