A while ago i have created a scenery for my small hometown in Germany. I have added a Hangar and a little Factory which i have modeled in Blender. They work well and are Visible from the Airplane even a few miles away from the City. Now i created a part of an old Castle on Top of a hill and it only becomes visible when you fly close to it. Once it is visible it stays vivible, even if you fly away from it again. Does anyone know whats the reason for that behaviour? Is this a setting in Blender or in the SDK ?
