nice looking version there Tveyes.
I think a few factors play in…I wanted to try the bike cuz it was a bit more complex than a head and see how they looked. I coulda spent days tweaking and having fun with each one. You are right…I didn’t fill in the back ground for yours for this test mostly because I started with some others first and baked each layer and didn’t want that to effect the final. Since light plays an important part you will also notice some shaders…when multiple objects are placed while having the same material will not show the same detail. Turning it away from the light…rotate em around and you will or can see sometimes significant changes.
what does that mean? find one you like and tweak it to your liking for that particular scene, becareful where you place the objects relative to each other and the lighting, play with colors and curves to get the desired look. It’s fun and can sure load up Zmats in a hurry with versions you like!!
