A visitor can be used to apply specific shaders to the parts of a model. If names were given to parts of the model by the modeling program, the visitor can look for substrings "_shader_metal", "window", etc, using osg::Object::getName().
A better way is if modeling programs could output .osg format with GLSL directly but none do AFAIK (??). >Hi, I was wondering how models have shaders applied in OSG.
