basic gloss to roughness question (principle shader)

Recommended Posts

Hi,

I have some basic question.
How to convert a glossy reflection file texture to a rougness map using principle shader?...

I know its the invert of it.
I tried different things... add a minus to the roughness slider at the top level (didnt work)

Allow edit of content  -> Adding a invert Node to the roughness node (gives a red "!")

Allow edit of content  -> multiply by -1. (gives a red "!")

thnx

complement node? (1-x)
you can also use a fit VOP: 0-1 > 1-0
