Problems with saved Irr. maps

[digitalx3d]

We are trying to render out an animation (arch. fly-by) using a saved irr. map. We calculated the map first using multiframe incremental, every 20 frames. Then we set the first computer to render the whole sequence from frame 1. Then we loaded up the same scene on 2 other computers and set them to render frames 200-300 and 301-450. We rendered out the first frame so that there would be an irr. map in memory, and then we set them to render the remaining frames using the saved irr. map. The first computer is still rendering out the frames perfectly, but the other 2 are somehow not correctly using the saved map because there are splotches all over the place.

Can anyone tell me what we're doing wrong??

Thanks!

I would imagine because they didn't start on frame one? there are others here more knowledgeable then I about these things.

Well, that's one thing I was wondering. If that's the case, what's the correct way to do it? Only Backburner will work?

I do not get exactly what you were doing by "messing" like that between computers and Imap. Sparing time ? Anyways, that's risky.

The right way to go would be (for my own)

1) compute an IMAP the way you did, 20th frame, etc... (even with a backburner job), save the imap on a network location.

2) Set a network job rendering all your frames and loading the imap you've set before.

3) When you'll submit the job n2 on your farm, put a dependency on it if n1 is not finished (then, it'll start only when the imap calculation will end) or launch it immediatly if the imap is already computed.

It'll work fine if your 3dsmax configuration is the same on each pc (plugins, bitmap paths, etc).

Good luck.
