SCNParticleSystem time source

Is there any way to create a SCNParticleSystem that would use the scene time as source and not system time? I couldn't find anything in the documentation or by searching various forums.

I can create animations that use scene time and I can obviously manipulate or nodes manually using the scene time, but not the particle systems. As a workaround I implemented a particle system that uses separate nodes and geometries but it's terribly inefficient for obvious reasons. The built in particle systems are not implemented that way.

Thanks,

Piotr

I've found an approach:

You can you warmupDuration and reset to simulate seek function

particleSys.warmupDuration = timeYouWant
particleSys.reset()
