The terrain is not the expensive part - it's the volumetric clouds. The shader I wrote samples a layer of the atmosphere. Within that layer (3000 to 6000 feet) I was sampling 20 points (3D volume points of the procedural pattern) to assemble each pixel.
20 is not enough to get rid of all sampling artifacts. At 100 samples, it totally is clean, but it's very slow - obviously 5x slower. My 2K image would be 10 hours. The full size 10K would be 63 hours.
But if I built a customized renderer that did that and nothing else, I figure I can make it 1000 times faster.
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)
