The shader has a sampler2D uniform that needs to be set to the texture unit you want to use; as long as you attach a different Texture2D to each geode/drawable on that texture unit, the shader will see that geode/drawable's texture. You only need update callbacks if the texture changes from frame to frame. -- Bryan Thrall FlightSafety International [email protected] _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
