Spatial Mapping Observer

The Spatial Mapping Observer allows the developer to set how often the spatial map is updated and contains three main parts:

  • Triangles Per Cubic Meter: This is exactly as the name states. The higher this number is, the more triangles you will get, but also the higher the performance hit your spatial map will cause.
  • Extents: This is the observable area from the camera's position.
  • Time Between Updates: This is the amount of time the system waits for before it accepts updates from the surface observer.
