Animation completely breaking when played in game

[RavenclawHermitCrab (Ethan)]

I have a viewmodel animation and it plays fine in the animation editor but when i play it in game, it
completely breaks. It may be something with the new roblox updates with animations. Also, i was using the new channel animations shown in this post: [Enabled] Beta Release of the Curve API for Animation Authoring

Heres a video of whats happening

I don’t know if this will solve your situation, but it is worth looking at since i noticed similar breakdown in animation:

FE Gun Kit Animation Glitch

I’ve tried using different kits, watching videos, looking up more dev forum posts, even tried changing the priority, but have found nothing. Now, I don’t kn…

Hope it helps!

I was working on animations a few days ago and I had a similar issue where the animation would look different when I tested it.
For me, it was because there was a bug where ease in and ease out were swapped in the game. I couldn’t get a good look at the animation editor in the video but I would recommend swapping the easing directions.
