the source of the -1 is in the dae file. Problem is the dom code returns these arrays as domListOfUInt. One thing one has to do is check if an index contains -1 (readTriangles does this) and than discard it. But there is a bug, the comparison uses the wrong type UInt32, it should be domUint as otherwise the comparison fails on 64bit system. If you haven't got one I can quickly generate the patch. kind regards gerrit ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
