Please share more detail of what you’ve tried, and what you’re hoping to do. I’m not sure what a sky component is… Are you asking about React Three Fiber? There is a dedicated R3F Discord that may have more people familiar with the component you’re using.
But my guess would be that animated shooting stars means creating some objects, giving them an emissive material, and animating them. There are tutorials and examples for all of these things, so you may get better help by getting started and sharing your progress (with code or a demo) when you get stuck.
