. Finished energy exchange between neighbor probes!
 => Looks quite nice, not as surprising as expected but nice.
 => Propagation of dynamic lighting's bounces across several frames is just not perceptible, this is very good!
. Added a dummy bland ambient for the sky when enabled but indirect lighting is disabled, just to be a little bit more fair than showing a black ambient
 => Anyway, the difference between On/Off is just mind boggling so no use to add to the drama
