UK2000 Scenery has announced that dynamic lighting for Prepar3D v4 is now available for their London City (EGLC), Leeds Bradford (EGNM) and Luton (EGGW) sceneries. These updates bring further comparability to the 64-bit Prepar3D v4 platform, as developers continue to take advantage of the features of the new sim. These updates (and thus dynamic lighting for these airports) are a separate download, and must be installed separately (by doing so, UK2000 makes them optional). To install dynamic lighting for these fields, login to your UK2000 account and click the "Dynamic Lighting Mod PrePar3d-V4" link.
Again, dynamic lighting for UK2000 airports are seperate downloads, so if you want dynamic lighting, you must install them after the base scenery using the method described above. It is worth noting that dynamic lighting, while realistic and good looking, does come with a performance hit.
