scan mtl options greyed out

is there any way to edit scan MTLs? there are multiple checkboxes in the scanned mtl node but none of them are usable

is this because i dont have a chaos scans subscription?

Hello @sean_krouse , You are correct in your assumption that this could be a licensing issue. The Chaos Scans plugin comes bundled with V-Ray by default, but in order to edit scanned materials, you would need an additional license.
