I'm trying to animate an NPC model that's using an R15 rig. I haven't had that much luck so far, but I was wondering if it matters if the model is anchored or not if you want to animate it.
Here's the script in case I need to make any changes if anchoring the model doesn't matter. It's a regular script inside of the model's humanoid, and an animation is inside the script.
id = "rbxassetid://549955265"
Example = game.Workspace.ExampleCharacter
Animation = script:WaitForChild("Animation")
Animation.AnimationId = id
local animationTrack = Example.Humanoid:LoadAnimation(Animation)
animationTrack:Play()

I am not sure but I doubt it matter if the limbs are anchored. An animation is just a simple way to lerp cframing, and cframing works if anchored.
Try animating an R6 rig, see if it works out. If it does and you applied to same methods, perhaps it's just with R15? I haven't tried animating R15 yet, so I don't know.
I tried using an R6 rig as you said, however it didn't seem to change anything. i think there's something wrong with my script, but i don't know what.
If a limb is anchored it won't animate. If you don't want the NPC to move, just anchor it's HumanoidRootPart.
