Keying Physics Determinate ?

Pentacles

Hello,
I looked on the forum but couldn't find anything, I was just wondering if it was possible to capture the “determined” position, rotation and all from a physical constraint.
To be clear (it's a tail movement), I have the movement I want with physics, when the body doesn't move, unfortunately the movement is modified if the body moves and the result is not what I want.
So I wanted to copy/paste the tail dopesheet, so I could remove the physics but keep the dopesheet, if you know what I mean.

I tried to redo the position, but the result isn't natural, fluid, like the physics, it's a bit... jerky, unnatural.
Thanks for the help 🙂

To capture the "determined" position and rotation from a physical constraint in Spine, you can manually key the positions and rotations at specific frames. While Spine does not currently support baking physics into keys directly, you can manually add keys to the dopesheet to match the physics-driven movement. This involves playing the animation with physics, observing the desired positions and rotations, and then manually keying these values in the dopesheet. This approach allows you to remove the physics while retaining the movement captured in the keys. Although this process can be time-consuming, it provides a way to achieve the desired animation without the physics constraints affecting the movement when the body moves.

Hey, I'm back
Right after sending the message, I set about redoing the animation frame by frame, to get it exactly right (well, as close as possible at least).

Fortunately, my animation was “only” 20 frames long. It took me about 1H20.
The result is ok. Here's my method for those who'd like to know:
1) I made a duplicate of my character, superposed them and copied the animation frame by frame (65% of the time) manually.
2) Once I'd copied the animation, I first arranged the start/end so that it could loop nicely (5% of the time).
3) Then I removed the physical constraints and did another shift, in the opposite direction.
Using the dopesheet, I looked at the highest and lowest points, which I copied, as well as the start and end frames, of course.
Using the dopesheet, I tried to redo the curve so that they were identical (30% of the time).

In the end, I've got an animation with around 6 keys per bone, which means I can slow it down or speed it up easily, whereas the frame-by-frame animation wasn't great, at least for this.
The 3) is optionnal though, it can be skipped. The animation is still not as great as the physics, but since I couldn't make the movement with the offset, we'll just have to deal with it (It's more a rope moving than a simple tail, there's multiple wave at the same time, it looked off every time I tryed to make it with offset)

It took a while, though, and I'd have appreciated a tool to do it automatically.
I used an automatic translator, so I'm sorry if some sentences are weird or a bit mean.

Have a nice day
