Hey Robert, Thanks for your email. I understand your idea but when getting down to implementation level I find a couple of problems. Excuse me I am a freshman in OSG.
1) When creating a Registry::ReadFileCallback, how do I catch the readNodeFile call? did you mean readNode method because I looked down to the source code and thatz the only method reads node. So I guess I need to apply optimizer in this method. 2) When applying optimizer, osgUtil::Optimizer::TextureVisitor can not be instantiated and I could not find any settings related to NPOT either. I appreciate if you could please give me more hints on implementation. Thanks Charles
