It recalculates the lightmaps on the fly after light positions/values changed, but without shadows. Tim Sweeney
mentioned something about UnrealEd's lighting algorithm and it sounded like VLight.

Bert: Rendering static lightmaps in Radiant would be the goal, so yes, a lighting compile would be necessary.

| realtime in UED allows surfaces with a lightmap already (prerendered) to accept realtime light from a new pointlight,
and to move existing pointlights around. i don't know exactly how it's done, but i suspect it's a texturing method like
bert mentioned... when you do move or put a new light in, it casts to all facing normals in its range even thru solids
that would otherwise block it.
