Syntax

float LightFalloffExponent

Remarks

Controls the radial falloff of the light when UseInverseSquaredFalloff is disabled. 2 is almost linear and very unrealistic and around 8 it looks reasonable. With large exponents, the light has contribution to only a small area of its influence radius but still costs the same as low exponents.
