Particle Flow caching and rendering slows until coming to a complete stop after frame 97 out of 500.

I have been trying to render a scene for the past two weeks that is just nder 2 G but has a particle emitter that leads to the collision of the particles with 21 deflectors. If I delete the deflectors, it renders fine, but I need the particles to collide and stick to the deflectors. My hardware is fine according to support, but no solution to my problem yet. I am attaching a screen shot of the Particle View.  Any ideas?

Perhaps worth a test: is it possible to combine those 21 deflectors to a single object and define that as one UDeflector? Maybe it makes a difference...

Thanks for the thoughts. The different deflector objects need to tumble
into the scene independently and interact with the particle system, so I
have not yet figured out how to combine them into a single object.

Im guessing, you have "lets say 1000 particle till 97 frame", then Spawn operator creates more than your computer can handle. try to have less spawn or particle.. or Jump into Tyflow 🙂

cheers..

The problem does only appear with activated deflectors, so either the deflectors cause the problem or the particle-generation after the Collision, most likely the Spawn (by Travel).
So

• try a render with a reduced Step Size in that Spawn
• try raising the Upper Limit in the PF Source-node

Thanks for the suggestion. I will give it a try.
