Delete selected particles in cached Pflow

#1

Hi there,

I´m doing a complex mParticles sim right now with lots objects colliding.
So naturally, after caching with the “cache to disk” operator, I noticed some particles covering up the camera.
So what would be the correct workflow to remove only those particles, without the need to recache the whole sim again?

I tried putting a delete operator in each event, set to only delete selected particles and then put that in the post cache operators list of the cache disk operator.
I then selected the stupid camera obstructing particles, but apart from selection taking forever, nothing happend…

I also thought about using a split selected operator, but I can´t select that operator in the post cache operator list.

Any ideas?

This seems to work…

Cool! Didn’t know that. Thank’s for sharing dude.

Yeah, I really need to figure out Data ops…I´m doing a lot of medical animations and there is often a lot going on with particles which I can´t get done with basic standard ops…

There is not much training material out there though and I´m always having a hard time getting by with just the manual…

By the way: I love your Youtube/Vimeo channel!
