[Animation] Sidestepping / Strafing causes legs to unexpectedly judder and shift violently

Zyro1331 commented 4 weeks ago

Describe the bug?

When strafing slowly or at regular speed, my avatar will repeatedly nod its head while the feet keeps immediately resetting its placement. My personal avatar has a custom animation config applied to it, but this seems to be replicable with default settings and other avatars too.

Here's my personal avatar exhibiting the behaviour.

Now this is a default Full-body Reference avatar, that also has a default animation configuration.

To Reproduce

Wear an avatar, preferably a biped avatar with no custom animation configuration or special rigging tweaks (like digitigrade legs)
Get a mirror from the Essentials folder, and set it to wide.
Now slowly strafe in front of the mirror, and watch your legs strangely judder all over the place. -- You may try different speeds, but sprinting may reduce the effect of the juddering as your legs move more rapidly.

Expected behavior

This was not a behaviour seen in the previous version (Beta 2024.9.10.682) in my testing and configuration of various avatars. It seems that the stability of the legs has reduced quite a bit in the latest version.

Can you replicate this with the debug visuals enabled?

Zyro1331 commented 4 weeks ago

Here's the behaviour with Debug visuals enabled.

Here's the same walking but with a SimulationSpeedRatio of 0.1

At 0:16 on the last video, you can see the Debug visuals show three footsteps suddenly register, which might help explain the rapid switching / resetting of the feet when walking sideways

Thank you! This should now behave much better in 2024.9.12.772!
