BB shader is a greyzone I think. As example his floor shader. He had a thread for his floor shader. With mat.formulas etc. This shader I build from scratch in his Matmatic script.

Is this now my shader or BB?

The other hand, we have X- math.formulas where we can build great scripts, nodes etc..what If all the people who find out those formulas would copyright them? We would still stick with primitive tools and sit on trees.
