Hi, I am currently working on Vadsoe airport in Norway. this is a small airport where wideroe operates regional flight this scenery will be a lite scenery (Not highly Detailed) and will be made for FSX , P3D (all versions).
Hi, I will release this for a small price on sim market, and it is currently work in progress.
I made the terminal in Sketchup so you have an in-app option to apply custom textures since now I moved to 3dsmax the tower was made using it and I applied textures to it via Unwrap method and I made textures in photoshop. you can take basic textures from textures.com and modify them according to your own need.
as a starter, I would recommend you to use Sketchup if you want to make custom buildings you can follow SoarFlyConcepts or AustinSass videos on youtube.
