Question about Neil Hill scenery

I installed Neil Hill's Pacific Northwest Airport Upgrade. I like that it adds vehicles, people and planes to many airports in the area. Adds a bit more life to things. I noticed though that there are no textures at night for the planes. I am not sure if this is by design, or I need to enable something. I don't know how these sceneries are developerd.I would contact Neil Hill directly, but the email at the bottom of the ReadMe must not be correct because my email could not be delivered. Any ideas on how to enable the textures at night would be appreciated.Thanks,Scott
