Advanced. When a model is influenced by more light than allowed, or when it reach the limits of the light (attenuationEnd), the light can be darkened according to some threshold. The resultLightColor begin to fade when distModelToLight== attEnd- threshold*(attEnd-attBegin). when distModelToLight== 0, resultLightColor==Black. By default, this value is 0.1f. Setting higher values will smooth transition but will generally darken the global effects of lights. NB: clamp(value, 0, 1);

Advanced. When a model is out of [AttBegin, AttEnd] of a light, the computed influence of the light used to choose "best lights" is not constant, and is a function of distance multiplied by a factor you can setup here. Default is 0.1f and is good for lights with att like (50, 100) (arbitrary).
