Rendering an animation without revoxelizing?

It's taken me days to realize why my animation is so slow compared to my calculations but I've realized that it's because of voxelization time. If I have a big chunk of .MXS scenes where the geometry is all identical but only the camera moves around is there a way to get maxwell to only voxelize the scene once?
I tried the Animation setting via the network manager and that voxelized each scene. I tried the Batch setting but it crashed the Monitor so I'm not sure what that would do. The batch script is also revoxelizing. Any other options I've missed?

As far as I know, since Maxwell is a view dependent renderer, voxelization must happen anytime there is a change in view.

Then wouldn't FIRE have to revoxelize each time you moved the camera?

Hmmm I can't test it now. Does FIRE keep rendering seamlessly when you move the camera? It would be a big optimization if animations could be handled this way.

Well, there is a pause, but not a revoxelization. I think the pause is mostly to give you computer resources while you pan around. Once you stop panning, it goes back to refreshing the FIRE preview.
JD has written a script for SU users along this vein. Thru SU you can create an MXS file which contains your geometry and a huge number of cameras (1 per frame) all in the same scene. JD's script apparently runs this animation without revoxelizing but that's all within a single MXS, which I don't have here.

At the moment Maxwell treats animations as a series of scenes. Although it can know a series of scenes go together, it can't know they're exactly the same scene with a different camera view. Scripting sounds the best way to go, like JD's script.

i assume that there is at least one person at NL who knows the answer...

It is rather not possible. If it is right and anyone know this secret then this one person would give us answer. Because this is what close forums are for. To contact developers with many customers in one time. so there are two explanation.
One - no one in NL knows how it works (mayby outsorce code from India)
Two - no one in NL reads this forum in few days (sjesta time or christmas already ? )
try to decoy them

always start a new thread with some compliments about stunning feautres, and when They appeared to give smiles and hugs .... BUMM ... start questions. It should work.

Ah, the old compliment-ambush thread strategy... works every time
Best,

Great start Brodie

I think at least half of NL crew would "accidentaly" step into Your thread

inlcuding even guys from "realflow wing" and cleaning staff
and yes Jason

I did not invented that

, but I see You are familliar with this strategy too.
