Blender 2.83 smoke or liquid simulation not showing up when switching to Modular mode
Confirmed, NormalPublicBUG


System Information
Operating system: Windows 10pro 64 bit
Graphics card: Nvidia GTX 960

Blender Version
Broken: 2.83, v2.83.0
Worked: 2.82

Short description of error
When I'm simulating smoke or liquid. If I switch to modular mode, the bake the simulation. I do not see any smoke or liquid after it has run the bake. I can see the domain moving as if particles are filling the domain, but during play back nothing is there.
If I change the mode to replay mode. I can see the smoke or liquid as it is simulating. But I don't get this in modular mode
I have a youtube video link that shows the problem.

I like modular mode, because baking the simulation this was takes less resources by not updating the view port.

Exact steps for others to reproduce the error

  • Create a box.
  • Duplicate the box.
  • In physics tab... Make one for the emitter and the other as domain.
  • Scale domain as necessary.
  • By default Blender is in Replay mode. Change it to modular to get the Bake buttons.
  • Bake simulation.
  • Then change scale of emitter and bake simulation again.


  • open attached file
  • Try see simulation with Replay (it should work)
  • Then try with Modular

Just to make sure we are all on the same page: could you share your example .blend file?

Yes I can. How shall I send you the file? Is there a place for me to attach it or should I just send it to you via link to my dropbox?

just drag and drop into the comment field (or use the "cloud" icon)
