Perhaps I'm using some archaic conversion method, using Deep Explorer, but my OBJs always wind up as triangles whichever direction I'm going in. That script sounds like it could be tres handy. I also seem to get vertices randomly unwelding themselves, but thats generally not that big an issue.
Yeah, going through Deep Exploration is probably what's causing the triangulation. As for the verts unwelding, are you using .3ds format anywhere in the process? 3DS format unwelds verts on UV seams since it only allows 1 UV vertex for every 1 "physical" vertex. If you get those OBJ import/export scripts for Max, you won't…
Yep, I was going to mention the same script. It'll probably get you 90% of the way there, but you might have to do some manual cleanup after you use it. Another option in Max is to make sure you have an EditableMesh, not EditablePoly, and use the Auto Edge funtion. Select all the edges and click on the Auto Edge button…
