Yes that's correct all node be them shaders or not are kept in the .mb file but if your spec was controlled with a texture file that would still need to be loaded............dave Well just re-loading the texture, transparency and specular seems easy enough if I'd pack the textures where they should be. It was the UV map I was more worried about, because then they'd have to re-arrange them to show the textures correctly and if I'd send it to someone who doesn't know how to work with that, it would be difficult.
