Thanks Fabrice, I'll see if I can get my head around creating a normal map from a hi- res model to lo-res in Prefab. Though as we know where the surface of sphere should be, is it not possible to calculate a 'perfect' normal map for any specific resolution model?
I figured out the lost contrast - I had to set the material reflectivity to 0 to get it back with a Dot3bitmap. Now I have a problem that the normal map shading shows up fine in the CS4 IDE preview, but when the movie is viewed in a HTML container (Win 7 Gadget), it does not appear at all :-( Regards Mark
