Hello, I've got a little question that I can't seem to solve looking through the docs...

Say I set the specular amount on a material to 20% then put a noise above it affecting specular amount with value one 0% and value two 100%. Does that noise alter the spec amount between 0 and 20, or 0 and 100?

Thanks!
