A quick update: I wrote a simple Java program that will allow you to reduce light on crowds ^_^
Tools is very simple it takes original crowd file as source and will output a new crowd file with % reduced ligthing...this is very useful to tune light on arena like the Barcalays Center...
Modded Version

Now the nice part is that those crowd files are composed of "entity" :
1 entity = 1 people in the crowd
The files stores upper crowd first then middle and finally courtside crowd....with some simple math formula I can even simulate much light on sideline and very dark upper/middle crowds...
RL comparison...
