I have Orbx's NCA scenery and have installed the demo version of ImagineSim's KSJC. Have you noticed that the ImagineSim KSJC scenery replaces the Orbx NCA off-airport autogen buildings with default off-airport autogen buildings to the west and east of the airport (too many mid-rise buildings)? I sent an e-mail to ImagineSim support and they suggested that I try removing the 'autogen_infill_01.bgl’ file from the KSJC San Jose Scenery folder. I did that and while it removes the default autogen, it suppresses any other autogen in these areas around the airport.
I'd really like to see the Orbx NCA autogen around the airport and through trial and error, have identified the Imagine Sim KSJC scenery files which are suppressing the off-airport autogen (ground_01.bgl seems to have the most affect in suppressing off airport autogen). Even though I only have the demo version, I assume that this result is maintained in the full version too. I'd like to purchase the KSJC scenery, but not at the expense of losing the surrounding NCA autogen buildings. Does anyone know if after I purchase the scenery, is there any way I can reduce the "footprint" of some of the .bgl files so that they do not affect off-airport autogen?
