Best quality surface lights?


(obsidian) #1

Just wondering, what kind of shader directives should be used to achieve the best looking and uniform light distribution surface lights?

For large area or strip lights, such as lava or trim strips, add these:

q3map_backSplash 0 0
q3map_lightSubdivide 128 // or 256

For small area lights, I recommend removing backsplash with q3map_backSplash 0 0, and using manual entity spotlights to augment the shader light.

I don’t advocate light-emitting shaders on models, where the large number of (small) triangles requires a really high q3map_surfaceLight value. Using trans shaders for the light emitting part and combining with an entity light using _deviance/_samples is the best way to go.

Hmm… there doesn’t seem to be any way of adding light jittering effects to surface lights - just skies and point lights. Is it possible to set deviance and samples to normal surface lights?
