Oh man, you are as busy as a bee, thanks for sharing your shaders with us :-)

I am thinking about using this for a background in a intro for my youtube channel, if I do it would be kinda annoying to give credit for just a intro, could I use it without giving credit?

thanks again for all you do. this is amazing.

Thank you! My virtual living room with your material is now wonderful.

Thanks - fantastic!! ...as really new to Blender - probably on of those dumb question - How to change the color of this concrete shader?? it leads to more general question - how to chcange color in procedural shaders?
