hehe, I'm really new to the material room. I've been able to add material to items, and even change colours of hair and clothing, but I don't know anything about nodes yet. I've tried to play around with them and managed to get a sorta kinda reflection in a floor, but it wasn't very good. I still need to see examples and then duplicate what has been done in order to get the hang of things in that room. I am learning though. 3 months ago I couldn't even change the colour of anything :)

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
