This shows a new plug-in called pureLight. It does automatically unwrapping of meshes and calculates lighting and shadows for static lighting. It works with every mesh and is a proven tool. They used it for architectural visualisation a lot.

It is interesting how fast things happen there.
It is still no directional light mapping like Source or Unreal are doing but they said it will move into the same direction.
