How do I create a spherical terrain? Like Astroneer

My game needs a huge planet, which is a spherical terrain. It can also be edited in the game, such as raising, lowering and smoothing.Is there any way to achieve it?

Creating a huge spherical terrain in a game can be a challenging task, but it is possible to achieve with Unreal Engine 5. There are a few ways you can create and edit a spherical terrain in UE5:

  • Procedural Generation: You can use the built-in Unreal Engine terrain generation tools to create a spherical terrain. This approach involves using mathematical functions and algorithms to generate the terrain, which allows for infinite scalability and the ability to change the terrain at runtime.
  • Heightmap-based terrain: You can use a heightmap-based approach to generate the terrain, where a 2D image is used to represent the height of the terrain at each point. This approach allows for detailed control over the shape of the terrain, but it can be limited in terms of scalability and the ability to change the terrain at runtime. You can likely use stamps to modify the terrain during runtime.
  • Voxel-based terrain: You can use a voxel-based approach to generate the terrain, where the terrain is represented as a 3D grid of cubes. This approach allows for infinite scalability and the ability to change the terrain at runtime, but it can be more resource-intensive than the other two approaches.

It totally depends on the game, but Voxel-based terrain is a safe bet to allow for most freedom in terms of destruction and building.
