This is a PR for my development branch. Some features might be split out into separate PRs after some testing.

Currently this contains:

  • Simulation panel in scene settings.
  • New "Play with Preroll" operator.
  • Add settings in the node properties of the simulation output node.
  • Support baking/deleting individual simulations.
  • Support custom path and frame range per simulation.
  • Improved timeline drawing (also see #112232). The solution right now has the following features:
    • Collapsed view of all individual simulation states.
    • Shows when all simulations are baked.
    • Shows when only some simulations are baked, but not all.
    • Shows which frames have valid/invalid simulation data.
    • When the all simulations are managed in sync, the visualization is the same as before (only missing frames are visualized differently now).
  • Initial (empty) new outliner display mode for "Bakes".
  • New simulation reset behavior (see #112154).

Settings for each simulation zone:

  • Baking from the physics panel was still just use the scene range when I initially tested... not sure what caused this

  • instead on drawing two distinct lines I saw this when caching two different ranges. Not sure what this means:
    image

  • The Play with Preroll operator should never pause imo, but always just jump and play

  • We need to find a better UI solution for this button 😅

The way that the different settings and operators for baking are currently scattered around is worrying me a bit. We have settings in the scene properties, the physics properties and the node editor now. Either the scene panel or the physics panel should maybe move (?).

I'm lacking a bit the ability to inspect what range a simulation is now actually using. It's good that this is visible once the simulation is baked, but it would be good to see regardless of that, as depending on the toggles this could be either the scene range, the scene simulation range or the custom range.
would it be an option to draw the ranges of all simulations in the selection in the timeline as gray before they are baked/cached?

The physics tab panel could move, since the future of the physics tab isn't clear with properties moving to (nodes) modifiers, and the simulation cache didn't really fit there in the first place.

I generally agree, but it wouldn't fit to show buttons that are selection context dependent there... I guess once the outliner view is properly implemented it can just live there

Baking from the physics panel was still just use the scene range when I initially tested... not sure what caused this

My guess is that you forgot to enable the Simulation Range checkbox at first (at least that happened to me once).

instead on drawing two distinct lines I saw this when caching two different ranges. Not sure what this means

The thin opaque line is supposed to indicate that there is baked data on those frames (and consequently, the output might not be affected by changes to the input). On top of that it shows the valid/non-valid status of the non-baked simulations.

The Play with Preroll operator should never pause imo, but always just jump and play

I updated the behavior.

I'm lacking a bit the ability to inspect what range a simulation is now actually using.

Maybe something like this can help? It shows the frames that will be baked for this particular simulation.

would it be an option to draw the ranges of all simulations in the selection in the timeline as gray before they are baked/cached?

We probably could, but I won't implement that for now without having a better idea for how that relates to all the other information we want to show in the timeline.

To me that wasn't clear looking at the lines, the thin opaque line is too subtle imo. It should at least be made thicker. Ideally we would display the invalidated cache in a different, more clear way in the first place, like with diagonal stripes (similar to caution tape). But that's a separate topic.

Maybe something like this can help? It shows the frames that will be baked for this particular simulation.

I'm personally not a fan of showing dynamic information like that inside of a button UI-wise. Not sure if there is something in the guidelines about this, but it feels wrong to me. I'd rather put it below, like you did once the bake exists. Adding this as strips in the timeline can then still be added at some point, once there is a design.

Changes look good to me, thanks

What's your current plan with the outliner display mode? Since bcon3 is getting close

The feedback loops took a bit too long to be able to implement the outliner stuff unfortunately.

I'll create a separate patch for the stuff from this patch that is main-ready.

I guess this could be closed now, since the majority of the changes are merged?
