I got a custom character to spawn, here’s how it actually looks

I also got an animation for it, however, it doesn’t work.
But it looks differently on the game

This is my animate script(followed a tutorial, should work just fine):
local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local walkAnim = script:WaitForChild("Walk")
local walkAnimTrack = humanoid.Animator:LoadAnimation(walkAnim)
humanoid.Running:Connect(function(speed)
if speed > 0 then
if not walkAnimTrack.IsPlaying then
walkAnimTrack:Play()
end
else
if walkAnimTrack.IsPlaying then
walkAnimTrack:Stop()
end
end
end)
I also get a HTTP 404 error on the AnimHandler, a script I think is on Roblox’s side.
Thanks!
