Improved the planet visuals in ExoSim! The planet now has a procedurally generated rocky surface with terrain variation, ridges, craters, and bump mapping instead of being a plain colored sphere. I also added a subtle atmospheric rim and changed the lighting so it has a proper illuminated side and dark side. The texture is generated directly in the code, so I didn’t need to use an external image. The planet still resizes, rotates, follows the tilted orbit, and turns into a darker silhouette while crossing the star.
