Please respond to osg users <[EMAIL PROTECTED] enegraph.net> Hi Werner, The colours on an osg::Geometry (passed to OpenGL via glColor or glColorArray) only take effect if glColorMaterial is off, but default in the OSG its on and set to AMBIENT_AND_DIFFUSE, but a default constructed osg::Material will switch off the ColorMatieral mode so I suspect you have one such material in your scene. See osg::Material and also OpenGL docs on glMaterial/glColorMaterial. Robert.
