Hi guys! I am wondering how to setup a material for my tommygun so that it allows me to Lerp, two different sections of a roughness map.
I am creating a Thompson gun and want to alter the black and white values of the metal and wood seperately. How would I go about doing this?

The node which I have selected is a mergemap which is a mask for the metal and the wood.
