It seems to me that this duplicated manner would be quite slow. I was
looking for a way to force the radiosity calculation to gather a high and
thus brighter value from the media. A media multiplier value. I was looking
for the location in the code that this value could be placed. I speculated
that it could be one location or many. I just did not know where to look.
