My sunlight was originally only set at a 38 degree angle (with zero degrees having the light pointing straight down at the ground from a noon sky position). It surprises me that at this relatively limited rotation I produced such a distinct part of the daily lighting cycle. I would have expected this effect at more around 50-60 degrees. In my reading though 50-60 is in the later sunset or rise part of the day...
I guess being from the prairies I have a slightly distorted sense of landscapes. In most places there are hills, plants, buildings, and/or mountains (which in fairness I'm used to the Rockies effecting sunsets in Calgary!) so the true 90 degrees is never going to happen. Mind you I come from one of those weird places that (at least for sunrise) an 70-80 degree emergence of the sun is possible. This last observation is mostly pointless other than I've expanded my lighting horizons (pun unintended :P). Cretaceous Alberta would have had a similar sunrise situation to its east due to the the inland sea... oceans being the one place I think of with a nearly 90 degree sun emergence event horizon.
So here is the new lighting scheme. Overall I actually like it more anyways. I'll have to do some work on the corpses shaders to better capture this lighting scheme. Also a few teaks to the gorging Gorgosaurus (in particular his arms).
While the old lighting scheme adds some mystery to the corpse, it also obscures it and the eating Gorgosaurus. So I think I'll be going with the new lighting scheme.
