I need to deal with vertices that are textured from multiple fotos or are never textured somehow on my side. Is there a way (without splitting the mesh) to assign a default material (simple color) to all untextured vertices/triangles? I'd assume that I can assign out of range UV coordinates (-1) and set a border color. Thanks for your attention. Best, Christoph
