FumeFX FAQ Page
Since there is always someone asking most of these questions on a weekly basis, here is a short FAQ. Please read it, it may answer your question.
Q: Why does FumeFX crash?
The most common problems:
1. You need more memory in your machine! If you are running less than 4gigs on a 64-bit machine you won't get very far. The more ram the better.
2. Use a 64-bit operating system and a 64-bit version of Max. 32-bit OS does not allot enough ram per process to run a decent simulation.
3. Increase your FumeFX voxel size (increase grid spacing parameter).
Q: But FumeFX says that it only needs XXX gigs of ram to run the simulation and my machine has XXX gigs of ram. Why can I only simulate to frame XXX
1. That is what FumeFX needs but what about the seven particle systems, collision geometry, and other max objects. Refer to question 1 answers for the solution.
Q: Can I have different colors of smoke within the same simulation?
Yes and No. As of FumeFX 1.2 there is only one shader per FumeFX Container. You cannot have two sources with two different colors. You can however use the Keymode Color range and have different colors within it.
You can use other third-party tools such as Krakatoa to shade and render your smoke.
Q: My Particle Flow particles are not moving when I use the FumeFX Birth or Follow operators
You need to export the velocity channel in the FumeFX General panel in order pass along your simulation motion to Particle Flow.
Q: Why isn't FumeFX creating any fire/smoke from my partilce system
1. The FumeFX grid spacing is to high.
2. The FumeFX Particle Source particle size is too small.
Generally speaking the Particle Source size should be close to the voxel size (grid spacing) in order to "see" anything happen.
