emissiveGiBoost property
Scales emissive surfaces' contribution to the injected radiance, so a
small bright emitter can light a room without blowing out the direct
image. 1.0 injects emission at the same strength it is shaded.
Emitters the camera cannot see contribute nothing under injection alone. Bake the field (Scene.bakeIrradianceField) for those.
Implementation
double emissiveGiBoost = 1.0;
