This picture contains all context, you see the StrafingAnimations are missing entirely.
When you load in (Playtest), you have the StrafingAnimations automatically loaded in.
However if you now call CreateHumanoidModelFromDescription on that same HumanoidDescription in your Character, it won’t load the Strafinganimations, it ignores “UseStrafingAnimations”.
I’ve just stumbled upon this issue while implementing a Custom Avatar Caching + Loading System
Expected behavior
It should respect the “UseStrafingAnimations” under “Players”.
