My Smoke Sim Keeps Making Gaps #92672

The only idea I had to fix the issue is to bump "Sampling Substeps" on max as its purpose I believe should be to smoothly transition to the next frame, but that's not what's happening. For 9 frames the simulation works as it should, but after that, it starts making gaps and I have no idea how to fix it.

Please help!

Hi. I tested the .blend file and I realize that after baking the Rigid Body with the operator "Bake to Keyframes" under Object/Rigid Body/Bake to Keyframes the simulation runs well with your settings.

I'm following the Rigid Body Simulation development enough to know that there are so many issues with it and it cannot be fixed in an easier way... a full rewrite of this integration will be necessary but there's no news(not that I know) about that...

Furthermore, I have a personal suggestion... I would turn on the "Initial Velocity" of the fire/smoke emitter to bring more realistic and interesting results in this case.
