Bagginsbill, short question only for general understanding: Is that Alitalia formula ... oops, KLM formula specific to cg rendered light ? Cause you have the light intensity in it. As far as I know in reality light will not operate in a linear manner. So doubling light at it's origin not neccessarily mean's to have the double quantity at the goal.
B.t.w. could you have a look to my material thread, please ... needing a kick ...
Actually it is linear. Doubling anywhere doubles it everywhere. I understand there is non-linear falloff with distance. However, the intensity of light striking a surface is doubled, regardless of the location or angle of that surface, if the original light intensity is doubled.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
