method advice large outside scene

[Adam H. Stewart]

I've bit of tricky situation. I'm rendering a couple of long animations ( 600 frames ect.) of a large outside scene. I was planning on using the fly-through method, Lightcache and Irradiance map. The problem is I only have vray scatter licensed on the on my machine and I don't have the time to sit and wait while I caculate the appropriate maps. I tried sending these down to the farm but they don't seem to be saving properly ( calculating on one machine ).
I 've been experimenting with using Brute Force and just sending things off to cook but the render times are enormous and the they super noisey. These are my settings :

Brute Force :

Subdivs : 16
Secondary Bounces : 6

AA Adaptive DMC

min Subdivs : 1
max Subdivs : 6

DMV Sampler

Adaptive amount :.85
Noise Threshold :.01

The scene is built to real world scale, it is a section of Scotland, with grass trees and a river. I've been working crazy hours trying and haven't really done my homework with how I was going to render the scene, I was counting on Flythrough :[

Thanks as always for you're help

I pretty much stick with IR/BF for outdoor scenes now. Try putting secondary bounces down to 3 and then just work as you would with LC - save the IR map in animation or add to mode, etc. Don't do BF for primary as well, the rendertimes will be awful!
