Its supose to look like this, they are not spritesheets but individual sprites that change sprites in the sprite renderer with an animator.
In the Unity editor it looks fine but when I see it locally I get an error that an animation cannot be played and it stays still.
You can use the VideoPlayer component to play a video. Just note that Videos and Spritesheet animation is not supported in iOS AR right now.
If you need that please send a feature request via Needle Roadmap. Quicklook doesnt support this natively. There are ways to make it work but we havent implemented it yet. If you can share more details about your usecase via the roadmap feature request it would also help in tailoring the solution.
Update I lowered the framerate to 4fps to make a spritesheet, but it still doesn’t work. It works in the local web but when I open the AR camera it doens’t work there
Im using an animator, I try to use a animation clip but it’s wroken
