博客介绍了Unity中灯光相关设置。设置成Lightmap Static时，烘焙低的LOD需在场景周围布置光照探头，否则低LOD模型可能显示错误。使用渐进式光照映射器时，无需在LOD组周围放光探针生成烘焙间接光照，但要让实时GI影响呈现器，必须包含光探针。

要设置成Lightmap Static

To make sure your lower LOD models look correct with baked light, you must position Light Probes around them to capture the indirect lighting during the bake. Otherwise, your lower LOD models look incorrect, because they only receive direct light:
意思是当烘焙低的LOD时需要在场景周围布置上光照探头,因为他们只接受直接光,如果不设置那么看起来就可能是错误的

Light probes placed around an LOD model.

When you use the Progressive Lightmapper, there is no need to place Light Probes around the LOD Group to generate baked indirect lighting. However, to make Realtime GI affect the Renderers in the LOD Group, you must include the Light Probes.(当您使用渐进式光照映射器时，不需要在LOD组周围放置光探针来生成烘烤的间接光照。但是，要使实时GI影响LOD组中的呈现器，必须包含光探针.)
