[osg-users] OpenGL ES 2.0 and LIGHTING

[Grigoriy Mylnikov]

Hi,

One more question. If I use gl_ModelViewMatrix in shaders to transform Light position, it gets transformed by both camera matrix and current node's matrix, that is not right.
Is there some build-in OSG uniform that holds only camera matrix or only model matrix? Or I should compute it and pass as my own uniform?

Thank you!

Cheers,
Grigoriy
