X An arbitrary number of dynamic lights is now supported. The maximum number of lights can be set through the max_lights variable (default: 100 for the beta version, 8 for the release version). The light manager uses the ABT for calculating which objects lie in the ranges of which lights, and generates lists of close lights for every object. This calculation, although very fast, is an additional rendering process that can affect the frame rate, depending on the number and ranges of active lights. For overcoming the 8 lights hardware limit, light sources are dynamically switched on and off during rendering while taking care that no more than 8 lights are active at any time.
Naturally, a single entity, block, or terrain chunk can still not receive light from more than 8 sources simultaneously. If an object lies within the ranges of more than 8 lights, it is affected by the 8 most recently created lights only. This ensures that creating a new light has an immediate effect on the environment even if many dynamic lights are already around. For using the new light system, levels and map entities must be compiled in mesh mode (Create Mesh activated). Terrain should be chunked; the smaller the chunks, the less visible are light swapping effects when more than 8 lights move in or out of the range of a chunk.
