OSG is capable of pushing and popping of texture attributes while traversing the graph. The same thing must also happen for the FBOs. Of course, some elegant solution which covers almost anything is better, however I htink only pushing and popping the FBOs is already what everybody needs ;) > > Also while I'm at it, something unrelated...

So not changing the default values in osgPPU, but just changing the texture settings later. Other way would be that you add this functionality to osgPPU and I would include it into the repository ;) Cheers, art ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=16069#16069 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
