I have got a animation with 4000 frames and I'm rendering it since 2 months :).
Now it is almost finished but I have to rerender some parts of the animation because of some mistakes with textures.
I just want to render trees and behind them just only the sky, but I would like them to be rendered quickly. There are no animations with these trees but I have a camera animation through this trees.
So which render settings should I use to render them quickly. I mean just the use of caches or other techniques that might make it fast.
