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
