A question of process - man moving cameras, static scene

[Adam H. Stewart]

I am working on a large outside landscape which has lots of trees and about 10 animated cameras. As nothing is moving in the scene I was planning on using flythrough lightcache and multiframe incremental Irradiance map.

The project is HD and the first render is 200 frames long, it took ages to calculate the 106mb file.

My question is - should I pre-calculate all the camera's into a single file ? - in theory this should cut down the calculation time but the file is probably going to be huge and I'm worried about it killing the rendernodes.

Any thoughts ?

Thanks as always for you're help

I would worry about having a super large irrad map file.

Thanks percydaman I was thinking it would create an issue - my machine crashed a couple of times creating the Irradiance, and the first time it did it screwed the map up, so it's probably better to sit through the multiple calculations rather then risk one big long one is going to fail

Thanks as always

look around for the imap control script. it will save your imaps individually. if it crashes, you can then just merge them together to get one good one.
