[osg-users] Transform matrix as Uniform to shaders

[Sebastian Messerschmidt]

Hi Nickolai,

In case you're really after the ModelMatrix you need to use the 
osg_ViewMatrixInverse and multiply it with your current 
osg_ModelViewMatrix.

As Robert already mentioned you need to set the 
osg::State::setUseModelViewAndProjectionUniforms(true) in order to make 
this work.

Cheers
Sebastian
