Luoshuang's GPULightmass

[anonymous_user_fbe2d247]

GPULightmass bakes directional lightmaps which should support normal maps by natural. But if you want the bounce calculation to take them into account or let the result be baked directly into lightmaps then it is not supported, and I probably won’t support that since it has been proved to cause many problems unless you are targeting low-end platforms like mobile where directional lightmaps are not supported by the UE runtime.

Currently all platforms support directional lightsmaps. Haven’t seen any case where using normal maps for light bake calculating would result anything but problems.
