Unity3d Game scene Optimization talk (2)

Dynamic real-time lighting is very resource-intensive compared to static lighting. So in addition to the dynamic characters and objects (such as can be beaten around the flying oil barrels) static terrain and buildings, all use Lightmap.

powerful Unity has built-in a powerful lighting map Baking tool Beast, which is the product of Autodesk Company (horrible monopoly, feeling and 3d of software to be plugged in one hand). It is said to have been used to make the edge of the killing strip and mirror.

Mirror edge of the architectural scene beautiful clean lighting, lightmap effect.

It is easy to make lightmap in unity, and you can bake them directly after adjusting several parameters. Support Gi,skylight,

first-Class effect!!! Of course you need a better machine, or you'll have to wait for a long baking process.
