Describe the bug

I just wanted to let you know that I'm excited about the new "flip_source_id" feature. However I think I ran into a bug I wanted to report (knowing that it's still work in progress and this issue might be obsolete while I type).

I rebooted my machine and I had Blender open and FLIP Fluids was calculating a simulation. After the reboot I reopened Blender and the file I had open before. Then I clicked "resume" and I have the impression that the information for "flip_source_id" was gone. Maybe you haven't yet implemented saving "flip_source_id" data for "resume"? I'm aware this feature is experimental but I thought it would be good to let you know anyways.

To Reproduce

(Force-) quit a running bake and then resume.

Expected Behaviour

flip_source_id data should remain in the simulation

Actual Behaviour

flip_source_id data was probably lost

Hi, thanks for letting us know! I wasn't able to reproduce the issue in just some brief testing. The data should be preserved after resuming the simulation, but there could be a bug.

Anyway, we are heavily re-working this feature and the data that is saved/loaded from the cache has changed. We'll make sure this will work.

Some extra notes for the Source ID and Age attribute:

• Support for particle sheeting with these features are not yet implemented.
• These attributes may not display correctly if the Particle Scale (FLIP Fluid Surface panel) value is changed from the default.
