That's the problem: Usually the most buildings just need day/night time animation, but this means to have another .xml. Even for a realistic looking small village we need up to hundreds objects with xml. This slows down fps heavy even on a high power computer system. As I'm already showed using .xml slows down heavily. > The ideal would be to coalesce all the buildings in a city > block into one model with one texture.

Though I'm not a expert, I always thought that X-Plane, MSFS and Co. uses something like a shader/ imposter for crowded areas. User want to have a good, realistic looking scenery for VFR. But how to achieve this easily? Cheers HHS > __________________________________________________ Do You Yahoo!? Sie sind Spam leid? Yahoo!
