I have read thru several posts and learned allot, but not a simple answer to this, so I am posting. I am modifying an existing airport (PAKT) and added several blended texture bmps with alpha. I used a flatten on the airport that matched the default and it all looks good and works great, but now I have lost all the autogen buildings and trees in a wide area, wider than I imagined! Is there a way to get it back, or do I have to lose the flatten? Seeing as I want the trees and the buildings, landclass isn't an option from what I can see, maybe I am wrong, please enlighten!Regards, Michael http://www.geocities.com/res052cd/cmhbanner.gif

Hi Michael.You can make an LWM transparent flatten BGL, and it won't exclude anything.Dick

Hi Dick, thanks for the reply, although I have read thru your tutorial, I wouldn't know how to go about defining the area and making the BGL for it, any help or leads as to more info would be appreciated.Regards, Michael http://www.geocities.com/res052cd/cmhbanner.gif

Hi Michael,I think that the exclusion of autogen is due to the textured polygons that you are adding and not to the flatten area itself.Kind Regards,Luis
