Looped animation on rig quickly reverts or "jolts" back to the default position before continuing to loop

Exactly as the title states; My rig quickly jolts back to the default “no animation” pose between animation loops. The animation is priority 4 and is looped.

Here is my script:

local hum = script.Parent:WaitForChild("Humanoid")
local animator = hum:WaitForChild("Animator")
local animation = script:WaitForChild("Blacksmith")
local debris = game:GetService("Debris")

local animTrack = animator:LoadAnimation(animation)
animTrack:Play()

-- Function to trigger spark and sound
local function triggerEffects()
	local sparkPart = hum.Parent:FindFirstChild("SparkPart")
	if not sparkPart then return end

	for _, v in pairs(sparkPart:GetChildren()) do
		local sounds = script.Sounds:GetChildren()
		local randomSound = sounds[math.random(1, #sounds)]:Clone()
		randomSound.Parent = v.Parent
		randomSound:Play()
		debris:AddItem(randomSound, 1)

		if v:IsA("ParticleEmitter") then
			v:Emit(50)
		end
	end
end

-- Detect Strike keyframe
animTrack.KeyframeReached:Connect(function(keyframe)
	if keyframe == "Strike" then
		triggerEffects()
	end
end)

Tweak the weight of the animation or increase the fadeTime parameter within track:Play()
track:Play(fadeTime, weight, speed) if I remember correctly

Alternatively it could be some strange issue with how you animated the character; try putting the initial (or idle) pose as a keyframe at the end

Tried it and it didn’t work, then realized I’m not the brightest, and that Roblox defaults ALL parts back to their original positions if they don’t have a keyframe at the start. Went through and manually added a keyframe for every body part.
