Those are some cool sunsets.

I tried that a few months ago. It worked ok, but you end up with the redish tint over everything, all the time. It's great for certain things as long as you don't change the time too much.
The beauty of the early lighting engine in CLOD is that the color changing was very natural. I really don't understand why they messed that up, as it didn't affect the performance much.
The thing is, I still have an older instal on a back up drive and I go back to it from time to time. When I do that, I end up pi$$ed and come here and post screenshots.
I still hope they will bring back those natural sunset and sunrise colors, without the need for filters.
Anyway, thank you Les for your tweaks. I think I'll go play with them a bit.
