The texture IMAGE units are the right ones. > Well, I just commented out (in the effects file) any reference to the noise > texture, or texture unit 9, and the errors go away.

May be osg confuses the traditional texture units and the shaders texture image units? Mathias ------------------------------------------------------------------------------ Ridiculously easy VDI.
