So I was reading in the unreal engine 4 siggraph paper about their usage of an empirical model for this.
If you haven't seen it it's on page 30 or so: http://www.unrealeng...mo_16x9_(2).pdf

Now the only thing I was wondering is this model as it is stated in the paper, is not normalized as it seems.
And as far as the code is concerned they only describe this factor for their area light sources.
Does anyone have an idea of what the correct normalization factor for this specific model would be for a regular punctual light source ?
