I'm using Blender 2.79 and there no longer appears to be a Cache tab under Particle System settings. How can I bake a particle system so that when Blender crashes I don't have to start rendering from the beginning? I'm not looking to turn the particles into real objects because I am not using physics, I need each dupli object to appear in sequence from the emitter object. Any suggestions greatly appreciated.
For those having the same problem: The cache tab disappears when the physics are set to "none" because apparently without physics, there is nothing to calculate and save to the disk. Because I was after the sporadic and stationary emergence of particles from the emitter, I found that using a Particle System of type "hair" instead of "emitter" will suffice when I animate the "length" option in the clump settings. It's not ideal because they all emerge at once, but until I find a better way, this will have to do! Please comment if there is a better fix to this!
I had the same problem. And I finally figured out, that you only have to check the box under Hair Dynamics (under Emission) and then the Cache-Option appears underneath. There is no need for animating the particle system! Which indeed wouldn´t make sense if you only use the particle-option to distribute a specific object in your scene.
