I'm seeing these same problems. textureSize2D appears to be a shader4 thing: http://www.opengl.org/registry/specs/EXT/gpu_shader4.txt ...so is this only going to work properly on new cards? Mine is only a year old, but I guess it's foolish to think it's not deprecated after that long... :) Attached is a log of the errors I get on my Quadro 2500M card. > Regards, > Kyungdahm > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >
