Hi Alexandre, Does the scene graph code you have inherited contain use of osgFX::BumpMapping?
osgFX::BumpingMapping It's a really ancient bit of the OSG so it's really how I'd tackle it these days but it provides the old style osg::VertexProgram and FragmentProgram. Have a look at the OpenSceneGraph/src/osgFX/BumpMapping.cpp so see what it's doing. Robert.
