Hi Chris, It's hard to know what is causing problems in your case as you don't provide enough information to know what might be amiss. In general, one wouldn't normally combine the built-in usage with vertex aliasing - the later is used to get the OSG to built alteranatives to the built-ins that are no longer available in OpenGL-ES 2.x onwards and OpenGL 3.0 core profile onwards.
