[Help] Animate part of character

Hi! So I’m a bit new to Unity & Blender, but I’ve been trying to make a 3D model for a game called VRChat. Here’s my question; how would I be able to add an “animator” to the model? I know this probably isn’t the best way to phrase it, but here’s what I’m looking at; I’m trying to get the model exported into VRChat I know how to export everything and that’s all setup. However, when I go to export it, I get this little message that says, “This avatar does not contain an animator, and will not animate in VRChat.”

Basically, I want part of the model to animate. In the game I ripped the model from, there is a bear and a bird. The bear is who you control, and the bird is your side-kick. Here’s what the two look like:

What I’m trying to do, is have it so the bird will flap his wings. I’ve created an animation with blender for this, and it’s already in Unity. (https://gfycat.com/OrdinaryQualifiedIcelandgull). So my question is, how would I be able to make it so the bird is animated, but you control the bear and only the bear?

First of all, there’s a dedicated forum for Animation, so you might try posing this over there: Unity Engine - Unity Discussions

As for your question, I would separate these two characters into individual models. That’s not to say you can’t keep them combined, but that’s going to make things a lot more complicated. Each character should have its own set of animations defined in its own animation controller, which you can play independent of each other. So, for example, you can put the bird on an idle loop where it looks around and occasionally squawks, regardless of what the bear is doing.

If you’re not familiar with the basics of animation, I’d recommend watching the tutorial series here: Controlling Animation - Unity Learn It’s maybe 45 minutes total, but explains how you’d do basic animation of a model.
