I have three flip fluid simulations with minor tweaks that I have saved out as .sim files. Then, in the DopNetwork I read them back in using three file nodes and used a switch node to control when each one is read. Now I would like to import them into SOPS where I intend to surface them.

The problem I am experiencing is that when I use the Object Merge, Dop Import, or Dop I/O nodes to read in the switch node all I get is the collision geometry and not the flip particles. Is there a button I forgot to click?

If you just wanna save your Flip particles and delete collision geometry ,So you can use delete SOP.

for example import your *.sim files via “Dop I/O” or “file SOP”.
Then add “delete SOP” and set Entity to Primitives and set pattern to *

Okay, that will get rid of the collision geometry, but how do I get the flip particles to show up?

I don't understand what you mean exactly !

When you delete collision geometry ,so you have just Flip particles now !

check my project ,Is this like your purpose ?

You hit the nail. I met the same problem. It turns out when I use file node to import .sim file, the ".sim" suffix isn't included in the list by default. Thank you very much.
