Fluid simulation result not visible after reloading file
Confirmed, NormalPublicBUG


System Information
Operating system: MacOs
Graphics card: Intel Iris Plus Graphics 640

Blender Version
Broken: 2.91
Worked: -

Hello. After I opened project, that I closed before, the fluid simulation didn't exist. It is very easy, to know the issue. Thanks for attention.

  • New file
  • Quick liquid effect on default cube
  • Save file
  • Close Blender
  • Open the same file again
  • The domain is just a smooth shaded cube until you play the file long enough for it to loop back to the first frame.

Thanks for the report. I can confirm this actually. @Sebastián Barschkis (sebbas) Any ideas?

Uh, this appears straight-forward but I'm not getting the issue. @Ivan Kostenko (KIOC) @Hans Goudey (HooglyBoogly) Can you add some more info? You are using 2.91.2, right?

Huh, good point, that was 2.91.0. However, the results on a freshly downloaded 2.91.2 are not any better, this is what I get after reloading the file:

Then after the animation looped back to the first frame I saw the particles and mesh again. Maybe related to T85409 (reported while investigating this).

Ah, thanks! With T85409 (after setting the frame to something that's not frame 1) I can see the issue too.

I'd say this behavior could be improved in 2.93. But since it's always been working like this, I'd say this is more of a "Known Issue".
