What's the secret to nice illuminated clouds, that don't let the sun burn through (creating a bright spot) but also provide ambient light for terrain?
I've always had issues balancing this. It seems Terragen's sun object likes to really pierce clouds, even with disc disabled. When I can get the sun to not show through the clouds, they're also too dark for any definition, and the ground is near blackness.
Overcast, not even full Cloudy Days, do amazing jobs hiding the suns location altogether while illuminating the surface. Take the Vikings and the need to create the "Sun Stone" to find the sun with overcast and clouds -- and other civilizations straight blind to navigation during these sort of conditions.
