 I have been trying to reduce render time. I have noticed that much of the render time is doing the GI pass. I did this one in two crop renders in about 16 hours. It's nothing special. I think it would have taken about 30 hours to render the full image without crop rendering.

Love the surfacing, particularly on the right - and the sky is great too.

There's great lighting here, njeneb. It looks like a real picture.
Heard of computer graphics? CG? Terragen 2, the landscape generating program, also known as TG, a whole cool way to create realistic CG - with TG.

I love the sky on this one. Pitty you can see the line down the middle where you did the two renders.

It looks realistic to me , Njeneb  :)
I can see the line too. How is it on your screen?

Shit... Thanks foor pointing this line out. I'll have to do some thread chasing.
It may have to do with how I merged the two halves in Corel Paint X. I did not erase the black areas. I just used a Screen merge.

That's the common GI mismatch between crops(same as animation flickering), GI is slightly different with each render. The best way around that, for the moment, is to use a good overlap portion per crop which you can softly erase the border of if there is still a mismatch with the overlap. Or, disable GI in favour of fill lights, that will completely stop it and a good overlap isn't needed.

It is a great sky, indeed. I also like the ground textures, maybe the rusty patches on the right slopes are a bit much for me but, great surface! :)

The line's only visible in the center of the image, thankfully

Or use Microsoft's free ICE compositing program - http://research.microsoft.com/en-us/um/redmond/groups/ivm/ICE/ - works pretty well at eliminating GI mismatches
