note: for each .anim
type => humanoid, model => copy from model
// to prevent player from rotating of to left or right => few changes
	- select animation.fbx
		- under root transform rotation
			bake into pose -> true (false if we rely on animation to totate character.... eg: run turn 180 )
			based upon -> original ((at start) if bake into pose false)
		- under root transform position(Y)
			bake into pose -> true
			based upon(at start) -> feet
		[apply]

[approach => apply root motion in animator]
