Surface Lighting
Surface Lighting, a feature available in most Quake-based engines is not available in the Unreal Engine.
Basically, Light Is emitted from a surface which has a shader containing all the light information.
It will cut time in the lighting period and light will be represented more accurately.
It could be possible with UScript but i'm no coder and i'm sharing the idea so it may be possible in the future.
