Re: [osg-users] disabled lighting after migration

Hi Sebastian, It could be that there is some undefined state in the scene graph that is resulting in some subgraphs inheriting that state from other subgraphs that are rendered before it. Make sure that all your geometries have normals/colour arrays as required by the rendering needs you have.
