Jepp Mike, the material in the first one is a procedural. Thank god, I saved it, so I can go back to this one easily:) I'm not happy with the cave myself. Maybe I'll try it with the spotlight causing shadows and turning the light in the cave off. hmmm.. Maybe I better turn the light into a spotlight too, I really don't want to loose the backlight behind the tree:) Thanks, the next version will render through this night:)
