Greetings.

I follow a Masterclass for Octane, but a low Version.

I still have a Hard Time to understand the Gadient Node. Should i use it in these renders ?

I got a ready Texture Set from Motionclips. At least it works.

Tell me if the Renders are good or if i have to use a additional Noded.

I am surely a Rookie in this manner.
