Hi all I am doing a new scenery of mkjs, how do I exclude the FS2002 default scenery (runway and taxiway ect.). I am using FSSC to do build the scenery, all so is there a way I can used other texture for my runway, I built some for my self.

In FSSC you can select Misc -> Exclusion. Then you can define the size of your exclude. If you make sure that it covers the default airport then you have got rid of it.I don't think you can choose a custum runway texture easily. You can select different types of runway textures from the dropdown list (grass, concrete, asphalt, etc). If you want to use you own texture I think you must draw the runway yourself with a normal polygon.
