    Hey there,

    I'm basically making a turret that fires "bullets" at a moving target. Damage is handled by code, so all the particles have to do is look pretty and appear to hit the target.

    I'm currently experimenting with caching the Main module of the bullet particle system, and then changing the particles lifetime to have the particle die as it reaches the targets position (lifetime = distance / particle speed).

    This is going on in multiple Particle Systems, potentially once per frame. Is this going to be doing horrible things to Particle System performance under the hood?

    Thanks

    That is fine. There's not really much benefit to caching the Main module, caching the ParticleSystem is enough although it won't hurt.
