Hello,

Now that the TextureCoordinate2 node is in place, I esalised that I'd
rather have a default grey colour of the faces when moving in the model
and the full texture when idle (or when using an Onyx :-( )

Peoblem is that if I put a texture2 node on an IndexFaceSet (or any other object)
that has a Material node as well (for the grey colour) I end up with a texture
dark and misserable since it is added on top of the coloured face.

Is there a way I could have a nice grey face when moving and a crisp textured one
when in high level of detail? WITHOUT using LOD that is. I can do it with LOD
but it seems to me a bit of a waste DEFing the object and adding it once with
the texture + white colour and once with a grey colour and no texture.

Cheers
