Hi Christian,
Where are these particles coming from? ex. Particle Flow, Thinking Particles, etc.
Krakatoa will not create any particle files at all if its licensing is incorrect. I believe Bobo was suggesting that whatever tool you are using to generate your particles is not licensed correctly on those machines.
The best way to test this would be to convert your scene to render your particles with Default Scanline instead of saving to PRT with Krakatoa. If the renders come out blank, you know that its not Krakatoa’s fault that it didn’t find any particles.
Let me know how that goes!
I edited my post’s first line to be more accurate. Bobo kindly reminded me that Krakatoa won’t create any files at all if its licensing is incorrect. See the previous post for more details.
Sorry to sound like a broken record, but Bobo and I are trying to stress that it might not be Krakatoa that is installed incorrectly. Have you submitted a rendering job to the farm that renders these particles in Max 2009 without using Krakatoa? In other words, have you determined that the issue cannot be anything but Krakatoa?
