Particle caching

I need to be able to take a particle emission sequence that I came up with and choose a part of it and have that be the entire thing and looped.

For a more detailed explanation the emission starts trickling out of the emitter then by say frame 30 it looks correct then begins again @ frame 60.

I need a prefab that begins @ frame 30 to frame 60 without that build up…

Can you not configure the system so it looks how you need at the start?
You can use the Simulate function to fast-forward to your required position.

Perfect Thanks!
