Issues with Additive Animation Blending for Running and Casting Spells

I’m trying to combine run and spell animations using additive animation blending. (Casting spell while running)

However, when I enable the additive blending option in the Inspector, my character’s skeleton behaves oddly (as shown in the attached video).

Disabling additive blending restores normal behavior. Does anyone know what might be causing this issue or how to fix it? I’m using BabylonJS 7.5.0

Here is the Character GLB with animations.

To use additive animations, you should convert your animation to additive by calling MakeAnimationAdditive. See the documentation for more information:

Thanks that worked! I think I need to mask some animations because, combining run + spell did not look so good.
