Poser can handle triangles or rectangles, it doesn't matter, but rectangles will tend to give you a lower poly count - it takes two triangles to make a rectangle (ok, it doesn't quite work like that but you get the idea). What Poser definitely doesn't like is polys with more than four sides. There's a program called DePent which will get rid of any of these 5+ sided polys. It's by A Appleyard and I think should be available in his free stuff here at Renderosity. If you're serious about making models for Poser then a really good book is 'Secrets of Figure Creation with Poser 5' by B L Render ('bloodsong' here at Renderosity). It doesn't teach you modeling but deals with all the problems of actually getting your model into Poser. HTH Mark
