I created the Asteroid by following a tutorial by Cartesian Caramel: https://www.youtube.com/watch?v=3ES0s71p_X4.
I created the Vignette effect by following a tutorial by Ryan King Art: https://www.youtube.com/watch?v=0RyaSB9qyL8.
I am currently using Blender 4.2, so I used a tutorial by Ryan King Art to recreate the Bloom effect for the Asset since it has been replaced with Ray-Tracing: https://www.youtube.com/watch?v=OhU-GV1CAF4.
