Procedural asteroid belt system for 3D and 2D space environments and games.

  • Supported Platforms
  • Supported Engine Versions


The SimpleAsteroidSystem (in short: SAS) gives you the ability to quickly add a procedural asteroid belt to your game level. It uses a radial chunk spawning system for the best performance, which means, it only spawns objects that are near your Player pawn(Follow Actor of the SAS). You can specify the spawn distances, chunk amounts, asteroid density as well as many other options directly in the spawned SAS Blueprint Instance.
