From what I gather, landclass determines what default scenery tiles are displayed. Does it also affect the type of buildings appear? I have an area with alot of large homes. When I use annotator to put autogen buildings in this area they appear as commercial looking buildings.Also, are autogen buildings alot faster than a small library of hand coded buildings with interchangable textures.

You need to have real small footprints to get houses -- I normally experiment with different sized footprints, discard the ones that don't give the result I want, and copy/paste the acceptable ones.Take a look here:http://www.windowlight.co.nz/ontarget/autogen2.html
