Hi All, I'm not too knowledgeable in the field of shaders and bump map, but lately I've had the task of fixing something related to it in our software.
The issue is that some faces in our software are bumpmapped (I see the 3 different texture units used in the .osg file, as well as in the original .flt model), but the node itself does not seem to have an osg::Program (nor osg::VertexProgram or osg::FragmentProgram) part of its stateset's state attributes. The question is this: is it possible that there is a way that a chunk of code of OSG could set up bump mapping on a node by itsefl and NOT add an osg::Program to it? For instance, if it finds more than one texture units in the .osg file, it would find a way to add a shader to enable the bump maping..? I'm really wondering how that node could be bump mapped... Thanks -- Alexandre Vaillancourt
