라이트매핑

Lightmapping is the process of pre-calculating the brightness of surfaces in a Scene, and storing the result in a Texture called a lightmap for later use.

Left: A simple lightmapped scene. Right: The lightmap Texture generated by Unity. Note how both shadow and light information is captured.

Lightmaps can include both direct and indirect light. This lighting texture can be used together with surface information like color (albedo) and relief (normals) by the Shader associated with an object’s material.

The data baked into lightmaps cannot change at runtime. Realtime lights can be overlaid and used additively on top of a lightmapped scene, but cannot interactively change the lightmaps themselves.

이 방식을 사용할 경우 게임플레이 시에 광원을 실시간으로 움직일 수 있는 유용성을 잠재적인 성능 향상과 맞바꾸는 것이므로, 모바일 플랫폼처럼 성능이 낮은 하드웨어에 적합합니다.

Unity provides the following lightmappers for generating lightmaps:
