This a a good base for a good add-on. Unfortunately it doesn't work as expected. The rotation of particles is not managed or it is in a wrong way.
Some improvement that could be nice IMO:
Allow user to change the frame range of the baking
Allow user to chose the collection for the baking
Move the mini tutorial in the properties panel to the preference panel.
Thank you for the feedback, it was incredibly useful!
Cake particles 4.3 now features:
a New Collection system management
a more user friendly interface, with just some tips under collapsed panels.
feel free to check it out and let me know if you find it easier to use :)
Regarding rotation and baking range, both of them were already implemented:
the range of the baking is = the range of the animation/playback timeline.
this is to ensure that the Cake Particles baking always matches the simulation one.
particle Rotation is supported in the addon, but kinda tricky to produce in Blender itself.
are you sure your particles are rotating to begin with?
Make sure to enable Rotation and check Dynamic to true.
Debugging with "render as Object" option is way easier when it comes to particle rotation :)
In any case cake particles should have no trouble keyframing any rotation in the particles.
If you still encounter issues would you mind sharing your simulation settings?
