Hey guys, I think I've seen this asked before, but I couldn't find it in a search.
Sunlight doesn't seem to be having any effect at all on the surfaces in my image. I've got a standard light setup (not changed any light or atmos. settings yet) and I haven't fiddled with render settings either but I do have some sexeh displacement.
I've checked and I know that the sun is not being blocked by terrain or clouds (no clouds) but the light doesn't touch the terrain at all.
If this isn't a common problem and you think the .tgd needs examining, just say and I'll post it.
