Hi PaQ, I have Modo 601, and a trial of the CAD loader. It did not generate a mesh with "all quads" at all, but loads of triangles. I could get the areas of triangles smaller by forcing a maximum length to the lines so it would dice things up more, but wanted to show here the results without that. The CAD loader did generate a mesh with good topology for reflections, but the bump mapping problem still remains at the corners. In the end the CAD loader n-gon output is quite similar in complexity to the MOI quads+tris output, but the MOI one is better since the bump mapping works. So MOI quads+tris is the best solution for use with Modo.
