Smoke simulation "Bake" is missing (or moved?) from 2.8.0 to 2.8.2

Blender Asked on November 30, 2021

I’m trying to do a Smoke simulation following the various tutorial videos I’ve found, and could do it in 2.8.0 (after figuring out I needed to delete a BSDF texture on the Smoke Domain), but since upgrading to 2.8.2, a lot of the settings have moved and/or changed names.

Most importantly, the “Bake” command is missing in 2.8.2 (or at least moved from where it was in the Physics:Cache menu in 2.8.0). I found a “Bake Animation” command in the Object:Animation menu, but this doesn’t seem to do what I need. When I render, it is always the same frame (somewhere in the middle of the animation).

See attached images for menu differences.

Any help/suggestions would be greatly appreciated.

2.8.0 "Bake"

2.8.2 no "Bake"

You need to change cache type for Modular or Final. In case of:

Modular - Bake button appears in settings

Final - Bake button appears in Cache tab (still under Physics)

Modular:

Modular

Final:

Final

It's now under Settings : Bake Data / Free Data.

Blender 2.82 use a brand new simulation engine (Mantaflow) for fluids and smoke, so any tutorial prior to this version is outdated.

For the given screenshot Cache > Type change to Final then the Bake option appears below.
