vmap_backsplash

Syntax

vmap_backsplash

Overview

Controls the percentage of surface light backsplash (how much light the emitting surface hits), as well as the distant away from the surface of which it is cast. This is really tricky to get right in tight areas, so put time aside to experiment.

The default backsplash amount is 5%, and the default distance is about 16 units.
