The shaders make extensive use of AO for the effects. By all means, do quick test renders without raytracing, but to see the full effects, enable raytracing and shadows.

I've included seven light sets. They use procedural IBL and one or two other lights. All use raytraced shadows. This produces the best results. However, if you feel you must use depth-mapped, go ahead.

Suggested Render Settings:

SuperFast - just to test lighting

Raytrace Off
Shadows Off
Pixel Samples=1
Min Shading Rate=3

Normal - for moderately good results at decent speeds

Raytrace On
Raytrace bounces = 2
Shadows On
Irradiance Caching = 50 (P7 only)
Pixel Samples=3
Min Shading Rate=1

Great

Raytrace On
Raytrace bounces = 2
Shadows On (and you're using raytraced shadows)
Irradiance Caching = 70 (P7 only)
Pixel Samples=3
Min Shading Rate= .5

Awesome - for final renders

Raytrace On
Raytrace bounces = 2
Shadows On (and you're using raytraced shadows)
Irradiance Caching = 99 (P7 only)
Pixel Samples=5
Min Shading Rate=.2

@BastBlack - I didn't include the wierd zone names yet. I want to test the basics first. I'll add them later.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
