light cache for animation

[gilicom]

Hello guys
when working with light cache for sec bounce
is all the information saved to ir map?
can i calculate a sequence every 10th frame using ir on incremental add + lc on single frame and then save onlt the ir map, then render the sequence using only the saved ir map and on sec bounce choose None?
i'm working on vray 1.46.15

Yep, that should work. I am working on an animation using that technique except I save the imaps per frame and then merge them with imap viewer. That way there is no risk of crashing like when multiple frames incrementaly.

Recent versions save the irradiance map at the end of every frame, so even if it crashes you will not lose the intermediate result. Computing a new map for each frame is a waste of render time...

right, ok my new reason is so that I can render them concurrently on several farm machines

I quess I am a little wary still from the past when the only way was to render the imaps incrementaly on one box all the way through , The options have definitely progressed!
