So, I worked out a relatively straightforward method using timewarp and timeshift SOP nodes in the Geometry network.

1. The DOP network generates particles for a finite period. In my case, I used keyframes to animate Constant Birth Rate.

2. Use timewarp in the Geo network to create cycles before and after. The loop should match the entire lifespan of all particles generated by the DOP.

3. Use timeshift after timewarp in Geo to offset time so the timeshifted particles are appearing while the originals are not, and merge the timeshifted cycle with the original. Presto!

Example attached. Hope this is helpful to somebody out there!

Hi, there! I'm trying to do the same thing and haven't had any luck yet. Have you made any progress? Thank you!

EDIT: I figured out how to do this using timeshift + timewarp nodes. Here's a link to my how-to post, with an example file.

Hi, Everybody. I'm in early stages of learning about Particles in Houdini. I expected to be able to find a way to cycle particle emissions every X frames so an emitter generates a repeating pattern, but I can't find an obvious setting and Google is not turning up leads.

I thought for sure this would be a simple feature. Has anybody done this before? Am I missing something obvious? Thank you!
