Randomized fog material (faster fog renders)

Postby Timo » Monday 3. April 2006, 11:30

I've noticed that people are having a hard time getting good fog with decent rendertimes, so I thought that I'd point you to a 'randomized' fog materíal in RS: it's in realsoft3d/tutorprojects/rendering/smokyroom.r3d
Basically you get noise instead of banding, but I find it produces better results than the normal shader. You can get rid of the noise by adding more samples or using more AA.
If you look at the VSL, you'll notice that the magic is done in the volume prioperties shader. If you remove the turbidity and color setting objects from it, you can pretty much drag and drop it to other fog materials.
When it is darkest, men see the stars.
