This took me couple of seconds to setup, not sure what you can speed up here.
Great, Thanks.
My problem was that it was solved.
I only had one wood texture and I had a lot of elements.
If I wanted to use a texture to diffuse for each element and its reflection, it will take me a long time.
I meant an option in multimap textures like( Hue random and Gamma random).
Anyway, I got my answer, thank you.
