The Lighting Vault
Well, after remembering a comment Mentat said about a lighting thread. I’m changing this thread from a lighting setup to a Home of Lighting Setups or…The lighting Vault!
I have quite a few settings. I even have a pretty nice and realistic render that I use for both preview and best render. I just feel it looks excellent in preview. But first, let start with a simple one light Super GDI setting!

Okay, after reading a few choice Pixolator’s threads, this is the product of playing around with the Material, Lighting, and Render settings. This is the same if not slightly tweeked settings I used in the artifact thread. All materials have about the same parameters. Same for the light.
Some info about the document:
:large_orange_diamond: Note the properties of the material used. From the ambience and diffusion curve to HDRI setting. You can select the right material by clicking the large material preview window in the Materials Palette and dragging it to a point on the document. The material is called Super GDI Mat. :D
:large_orange_diamond: Also note the Shadow settings of the single light used. Thats right...just one. GDI and light are maxed out and the falloff is adjusted as well as the ambience. Using only one light is something that I read in one of Pixolator's Pre-GDI test threads. Light is called Super GDI Light. :D :D
:large_orange_diamond: The document is designed to be at AA Half Zoom. The Rays and aperture reflect this. If you want to render shadows well at a normal zoom. Increase the ray count at about 150 to 200. Decreasing the Aperture setting to 25 and increasing the Blur to 5-7 will help as well.
:large_orange_diamond: File should work for demo users also though I haven't tested it. If it doesn't (due to custom canvas size) I will upload the full file when I get home.
:large_orange_diamond: Did I mention that its fast? Due to the amazing abilities of ZBrush, the rays can be set low and you will still have a decent render. Here is a tip for the final note. Set the rays to 3 or 5 when adjusting light positions and shadow lenght/intensity. This will lead to a superfast render. When your happy with everything set the rays and aperture to your desired number. This saves tones of time!
If you have any questions about the document or about some of the logistics of why it works then let me know.
Enjoy everyone and Happy ZBrushing!!
:white_small_square: Here is another test :white_small_square:
Super GDI 2
This is the one that looks decent with Preview Renderer. Zip includes material!
