Hey all, I've just completed a new hair model built from scratch in RayDream- Imported it to Poser3 as an .obj, then saved as a .hr2 file. I haven't tried it in Poser4 yet, but for some reason it keeps causing the dreaded C exception, access vioation error whenever I try to render it. This pic is the hair model in ati-aliased preview mode. It bombs on the shadow map build. If I turn off shadows, then it bombs on the render! It is rather large, but I don't think that's the problem, because I've rendered larger objects with no problem. The .hr2 file is just a little over 4 meg. Another thing, if I export it from Poser as .3DS, then the .3DS file will not load back, as it tells me invalid data in this .3DS. Other models I have made and done this way have never given me this particular problem either. Anybody got any suggestions? [b][i]I will post this model to free stuff if I can ever figure out what's causing this error.[/i][/b] Thorne =};-}>
