How can i activate the night textures with a vfr scenery because when it's night the ground is dark instead of showing the night textures. Some of my vfr scenery's does acivate my default night textures but the others don't... who can help me?Paul

I assume you're talking about photographic sceneries?Some of them contain night textures, others don't. If they don't, you will not even see default night textures because the photoreal textures override those even when they're completely black.All Megascenery products support night lighting. VFR Photographic USA San Francisco has limited support for night lights (point lights only), while later volumes in the series have full night lighting. Most European photosceneries like Switzerland Pro, VFR England+Wales etc. don't have night lighting due to the lack of accurate data.If the scenery does not support night lighting, your only option is to *disable* the VFR scenery in the scenery library when flying at night. If you have Ultimate Terrain, you can leave the photoreal scenery active and activate all night lighting options in UT and you will get VFR US Vol1. style point lighting (but no lit textures).
