I've made a few tests with the current (trunk) version of the exporter and I'd say it doesn't handle the normal maps for now. In Max, to use a normal map you don't assign directly a bitmap to the bump channel, you first create the map of type "normal", then assign the bit map to it. So there is an extra texture node to go through. I guess the exporter could be extended to check if the bump texture is not a bitmap in which case it could try to interpret is as a normal map. No idea how to do it though as I don't know the max SDK ... :( Luca ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39455#39455 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
