When I was learning how to use EdgesTex, I could not get it to work no matter what I tried. Then someone told me that you have to use ProOptimizer in order for it to work which did then start working for me. There’s a thread around here somewhere, but it was awhile ago… Maybe it was because the model at the time was coming in as something other than Editable Polys as I think about it. So then it sounds like I just need to make a different material for those parts I need to chamfer. Interesting.
