Implemented a "best effort" approach to the NURBS texture problem. Max and Maya do not seem to give a lot of importance to NURBS texture since in both documentations NURBS are viewed only as a mean of generating smooth polygon meshes. ColladaMax: I had two choices of data formats for NURBS textures: user defined (raw) and chord length parameterization (CLP) data formats, the later using the CV hull to give a better, more natural, texture coordinate information. Max does not take back its own data, despite what the documentation says. Wether I use raw or CLP format, Max screws the texture information, so I chose not to import it anymore and use the default setting. I'll contact Autodesk to see what's going on in there. The Viewer handles CLP data correctly, but Maya will not be able to import it (the rotation angle is ok, but the offsets and scales are incorrect due to CLP output). ColladaMaya: Added correct texture surface export. NURBS texture information is stored in the material's place2dTexture node. At export time, I build a default texture surface and transform it using the node's simplified rotation, translation and scale parameters.
