Hi Peter, If you want to override the vertex colours on the drawables (shapes or geometries) in your subgraph then you'll need to set the materials ColorMode to OFF. osg::Material::s/getColorMode(..) maps to glColorMaterial functionality in OpenGL so have a look at OpenGL docs to see the reason for this behaviour - it's a bit convoluted to type into an email.
