Light Mobility
The mobility setting changes how the engine handles lighting and shadowing.

  • Lights that cannot change or move in any way at runtime.
  • Lighting and shadows precalculated.
  • Memory for lightmaps.

  • Lights that can change some parameters but can not move.
  • Bakes light and shadows for static objects also cast dynamic shadows for moveables (only four overlapping)

  • Completly dynamic light and shadows that can change any proptery they have at runtime.
  • Lighting and shadows calculated almost every frame
