FTEQW Builds: Software Renderer OpenGL Renderer Minimal GL Build Merged Build Linux Build

Controls lightmap saturation. Defaults to 1.

Usage:

r_lightmap_saturation 0 completely converts all coloring in the lightmap to grayscale.
r_lightmap_saturation 1 preforms no change on the lightmap.
r_lightmap_saturation between 0 and 1 produces a lightmap with partial coloring based on the fraction given.
r_lightmap_saturation greater than 1 produces an over-saturated lightmap. Note that the lightmap will get darker to match or stay under the intensity of the original lightmap.
