- Tobba_ 9y agoFor reference, VSM/4MSM are a set of shadow mapping techniques that don't suffer from acne, at the cost of suffering from bleeding problems that also need biasing. Shadows are probably one of the places where raytracing makes a lot of sense though. It's one of few shadow rendering techniques that don't blow a ton of precious fillrate, and it shouldn't take too many rays.
