Need help creating on animation for this satellite

Hey, I’m trying to make an unfolding animation for my satellite using the roblox animation editor plugin. I did the rigging using this plugin:

The rigging is fine as far as I know, because the animation editor lets me select the satellite model. However, when I select it, none of the buttons on the animation editor work and it looks like this:

Is there some other thing I need to satisfy before the editor lets me work? The satellite’s rigging looks like this, and the middle box part is named HumanoidRootPart:

And this is what the hierarchy of the model looks like. solar and solar1 are the two solar panel arrays, and Model is the box in the middle. Again, the actual box part is named HumanoidRootPart.

I figured it out, for anyone wondering I just had to ungroup everything within the model and make joints from the root part to every individual part instead of in the chain pictured.
