[osg-users] trouble with flattening static transforms

I went ahead and wrote a visitor that really does remove all static transforms. If nodes underneath transforms have multiple parents, it makes copies so that each child subgraph can be properly transformed. On my big test case, I remove 911 out of 911 transforms, my model takes up 10x the memory,

Yes sure, I could disable lighting in that simple case (Yet I'm not even sure of it, I have no real example in mind but suppose I have an other sibling attribute also depending on GL_LIGHTING... ).

Hi, As others have mentioned you can bump up the notify level to see the infologs from the compile and link. There is also a method to directly query the infolog. The GL2Extensions contain the tests that determine of shading is available; you can snoop its results. That said, first thing is to

Re: [osg-users] osg::StateAttribute::ON / OFF forosg::StateAttributeor not ?

Not all attributes have modes, as you've discovered with Material. The current OSG paradigm of being able to setAttributeAndModes for Material really doesn't make much sense. I'd be reluctant to rewrite any portions of OSG dealing with the fixed function pipe, though, in light of OpenGL 3. To dis

It sounds like a graphics driver problem of some sort. I have successfully run osg 2.2 on a 7800 just fine. What OS are you using? If you are running Windows I would go to Nvidia site and try reinstalling your graphics drivers. I have seen driver installs get messed up. The shader you are usin

It's not clear to me what you're saying. Are you saying that even when you specify ON, fog is not enabled? Or are you saying that when you query the StateSet's GL_FOG mode later, you're not getting what was set? Or are you saying that when you dump the scene graph out to an .osg file, GL_FOG ON doe
