Release 5.8.0 2026.07.28

Back to release list
- Add support for direct (static lights only) and indirect lighting contrast (spherical harmonics smoothing) and intensity control
- There is also a per-light override for direct lighting contrast (static lights only)
Since the first version of GPULM, a stupid bug has caused direct lighting from static lights to be twice as intense as intended. It is now fixed.
Some technical detail:
Direct Lighting Contrast is mainly for removing negative values from the sphere, so 0 means the minimal value over the sphere is guaranteed to be >= 0.
Indirect Lighting Contrast is more like an artist control: 0 means removing all directionality and you’ll get the average value over the sphere.
