ok so i set my simulation to “cache to disk” and ran it..

i can see its all cached.

i go to my grain_particles net, select my ROP output driver, and hit “render to disk”

instead of exporting the cached simulation, it clears the cache and starts resimulating.

this is extremely annoying!

any help most appreciated. i need to export a cached simulation, as i need to export different particle groups with different rop output drivers. not exactly ideal to have to resimulate each time.

please help?

The first thing that comes to me is to see if you checked the “initialize simulation OPs” on the ROP that would explain it.

hi, thanks for the reply.. i dont have that checkbox ticked. anyway im now trying saving the cache using an output node in the dopnet instead.
