Hi mat,e unfortunately, it doesn't show in my project, just black screens, I'm actually using MGCs animation megapack and it works perfectly fine. And even your samplepack does NOT work due to the js file needed as mentioned above
I can help you with a live stream on Discord if you want to. I could show you how to install.As I said before, a js file will never prevent an animation to play in database.

Don't try to run the project itself, look in Database.
