  • Spot light : From a single point but limited by a set of cones
  • Sky light: Capture background of scene and apply it as light
  • Rect: Emit light from a rectecgular plane

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

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

Stationary
  • 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)

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