Imported fbx animations result in sliding feet

In blender, you can see that the feet don’t move at any point of the animation.

Here after importing into roblox, you can see that the feet slide around slightly through the anim.


I’ve tried to play around with the scale incase it was caused by that, but when I set the scale exact to what the animation was exported as, the feet still slide.

Any way to fix this? Cheers in advance for any help

Just how ROBLOX’s physics work I think.
