I would recommend using the osg_ModelViewMatrix etc. as these are fully
supported once you enable them and is far simpler than workarounds like you
are trying. All you need to do is enable the aliasing to get the OSG to
generate the uniforms. The osgsimplegl3 example illustrates how :
// for non GL3/GL4 and non GLES2 platforms we need enable the osg_
uniforms that the shaders will use,
// you don't need thse two lines on GL3/GL4 and GLES2 specific builds
as these will be enable by default.
Could you explain what the problem was when trying to the OSG's built in
