A youtuber make a katana animation that only the katana move but I cant make my own??

https://www.roblox.com/library/8075736675/AnimationPack-for-Katana he used these animations, the one I am referring to is "AnimatingSwords_KatanaR6_1"

https://youtu.be/hvCHa-ngB90

I cant see any keyframes in the animation once I exported them to his R6 character but the katana move. It has something to do with the Motor6D

I want to make my own animation that only the katana move too and I tried that by welding the RightHandle to the sword and export only the RightHandle Animation but it doesn't work.

here's the script that he used to connect the Motor6D, Katana, and RightHandle

Katana:SetPrimaryPartCFrame(RightHandle.CFrame)

			local Motor6D = Instance.new("Motor6D")
			Motor6D.Part0 = Katana.PrimaryPart
			Motor6D.Part1 = RightHandle
			Motor6D.C0 = Motor6D.Part0.CFrame:ToObjectSpace(Motor6D.Part1.CFrame) * CFrame.Angles(0,math.rad(180),0) 
			Motor6D.Parent = Motor6D.Part0

alright so I fixed it. In the script he play 2 animation at the same time the sword swing and the katana move animation.

I just use one animation for both and it works also gotta make the RIghtHandle motor6D
