but, threshold 0.1-0.9 does make it possible to regulate a quantity of active and passive luminous sources? and which as a result does give the threshold of higher than 1.0?
Well yes... If you have for example a luminous poly with 200% intensity you can set threshold to 2.0 or higher and it will be computed as passive.
As I said all light sources with intensity smaller than "threshold" will be computed as passive, those with higher than "threshold" as active...
