Ah ! Much better ! I've used the detriangulate utility on the original file, but this time setting the minimum angle at 20 (instead of the default 5), increasing the value beyond 20 doesn't give better results. Now I think the result is good (see link : for some reason, I could not post a new image in this thread...) Thanks a lot Little Dragon for pointing me to this wonderful freebee. nomuse : the rendering problem apparently occurs mainly with poser5's toon nodes. I remember having read that Poser4 also has issues with triangles, but I cannot remember which. I haven't had any problem in renderings triangles until this one. Thanks for your help. compiler
