Issue with animation playing only with keyframes with cubic easing style

I’m making a NPC that sits in a rocking chair and I decided to just make it all one rig and animate it. I have the animation made in the animation editor all the keyframes have cubic as the easing style with variable easing directions. However when I play the animation in a game it looks like its either jumping or not easing right. Here is what it looks like in the animation editor:
When its being played on a humanoid in game it looks like this:
When I switch the keyframes to linear, it looks fine when played.


As a temporary workaround, swap the EasingDirections in and out while editing your animation.

Hmm, yea since my animation could be represented with an inout easing direction I just used that and it worked.
Edit: If they do fix this would it break all existing animations that currently were adjusted to compensate for this bug?

I doubt they’d make breaking changes, they’d rather update the animation editor to show the correct animations and EasingDirections. Doing otherwise would break most existing animations on Roblox, that’d be too harsh.

Off topic, sorry to bump but I had to ask. Is this Kingdom Come: Deliverance music? I love that game.

It’s crazy this post was made back in 2020, it’s 2022 and the problem still hasn’t been fixed.


2023, still not fixed to this day
