DescriptionEdit

The WorldEnvt.ini files control visual tunings related to the sky, fog, and cloud cover. Colors for the sky and clouds are influences by separate color ramps. Builders may find that, despite not understanding what each tuning does, they can get nice effects by trial and error. However those with a clear understanding of each tuning's effect can share their research in the annotations below.

StarIntensity = 0 ManmadeLightIntensity = -128 ProbabilityWeight = 0.0 DaytimeBloom = 0.25

[CloudLayer1Params] VisibilityThreshold=0 Sharpness=0.995

Fog distance.
Fog equation is basically
f = saturate(((end - distance) / (end - start))
f = pow(f, curve)
color = lerp(color, fogColor, f);
start ;; distance fog starts at
end ;; distance fog ends at (no longer increases)
curve ;; modifies distance curve
fog = pow(fog, curve). (0.0-1.0 == increased fog curve, 1.0 == linear,

1.0-inf == more gradual fog curve)


[FogDistance1] start = 10 end = 1000 curve = 1 timeOfDay = 1

[FogDistance2] start = 30 end = 3000 curve = 1 timeOfDay = 6

[FogDistance3] start = 30 end = 4500 curve = 1 timeOfDay = 8

[FogDistance4] start = 30 end = 4500 curve = 1 timeOfDay = 16

[FogDistance5] start = 30 end = 4500 curve = 1 timeOfDay = 18

[FogDistance6] start = 10 end = 1000 curve = 1 timeOfDay = 20
