[stellab]

Ciao!
I have an issue, I don't know how to set metlaness in corona. I have a vray material with roughness 90% and metalness 70%, now in corona how can i set the same parameters?

Thanks in advance to all for the help.

Grazie mille
Stella

You can use a color to drive metal values so:
0.70 * 255 = 179 RGB value.

Thats my understanding.

Alternatively, if you don't want to do mental gymnastics, you can simply plug Corona color node into metalness slot and adjust its output level accordingly.
