Hello,
i am having Problems with Krakatoa and Fume.
I am using Fume as a followField and would like to cache these Particles with Krakatoa.
I cant get it to work though over the Farm, locally it works. When submitting on our deadline server the followfields dont get evaluated.
Now i would like to know, does the followfield get evaluated when i start a mayabatch job? Does it need a sim or workstation license or no license at all?
Thank you

Hello,
Can you please let me know if you're batch rendering or batch simming the FumeFX ?

Well, actually none of the two.
I am just baking out the particles this way. I am not running a fumefx sim, since it is already done at this point, and i am not rendering either.
I tried to submit the job on the farm with backburner mode on and off. Both didn't work.
Hello,
So you already have FumeFX caches simulated and you are using FumeFX follow field to drive particles?
We always recommend that particles are cached before other usage.
Thank you.

I think i have to be a little bit more precise.
I want to simulate around 100 million particles with krakatoa to get a dense particle cloud to render in krakatoa.
Initially i setup a fume simulation which i am happy with so far. It is cached and used to drive the particles that i have to cache now.
For the next step i have to use krakatoa, since i have to cache these particles 100 times (100 x 1 million particles). I could now do this locally on my workstation, which would work, but i would have to wait for the sim to run 100 times. It would take very long and would also block my fume workstation license.
Now krakatoa has a special deadline submitter that caches the particles for you, either through mayabatch or mayacommand renderscripts. Now for this renderjob to work the fumeFX followfield has to be evaluated aswell. And at this point fumeFx fails to work.
Now your suggestion of caching these particles is exactly the problem i have. I do know that this workflow works perfectly fine with 3DS Max, but doesnt with Maya.
Maybe it has something to do with the fact that maya particles do not cache properly with the "Create Particle Cache" Option and a FumeFX Follow Field? On the other hand krakatoa basically steps through the frames and saves out its own caches after each frame.
I also tried nParticles, but again as soon as i try to simulate over the farm the Follow Field does not get evaluated.
Thats why i was also asking if the follow field would work at all on a machine without a license when running a mayabatch process. Krakatoa for example does not require licenses for the caching part.
It would be awesome if you guys could look into this, because it is quite important when using fumefx as a particle driver.
Thanks

Hello,
do you think this is something you could have a look at for Version 4.0?
Thanks

Hello,
Yes, we are looking to fix as much as possible regarding FumeFX and particles in Maya.
If you have a scene for us that we could test that would be very helpful.
Thank you.
