Night Environment is a new product currently under testing at Aerosoft. It is intended to improve the FSX night flight experience, using a combination of lights (millions of them!) and textures.
Mathijs Kok from Aerosoft says that this product consists of a base layer and three additional layers and therefore it can be used on any hardware and basically will work with any additional scenery (including Orbx Global but one should turn off the Vector road lights). Also, Night Environment is compatibility with P3d v2, with a few issues with P3d V2.1 that are being ironed out. No release date has been announced yet.
