Nope, no cropped sections, Tom, I just left it running overnight as a full render.
It does look like crop lines though, I've experienced these many times but I'm always able to correct that afterwards with a little overlap in each crop region.
I do however crop little test sections of all aspects of my scenes before I render them final, these anomalies didn't show up though until I came to render it full.
I'm very dissappointed with it as the sky, in theory should be really nice and the bankings had lovely shadowing from the stones. God knows I spent long enough on it, I don't think I have the patience for re-twiddling all the knobs again just yet.
Maybe I'll bring it back when/if we see TG2 released...
I mentioned in another thread that the reflections on the wet stones didn't translate very well on the other side of the bank... This is definately a GI thing, with GI enabled there is a silver sheen to the far away bank, like it's coated in specular plastic, this doesn't happen without GI and the stones have the correct reflection properties, i.e. dark, wet stones with brighter highlights, as opposed to light, plastic reflectivity with very pronounced highlights. Balancing all these issues is a task, especialy when I really need GI for the cloud layers, they're very flat looking otherwise.
AAARRRGGGHHH!!!
