The Zip File includes 3 Files. "Airfield2.blend" is the origin file where you can make changes. Day and Night are presets for Night or Day renders. Everything is Blender Internal. So basicly it's just a texture pack, but i decided to build a simple scene to see how they can be used. all textures are CC0 (zero) and i built them al by myself. So what textures do you get? corrugated metal, brushed metal, fence, tree, stoneplate (most of them with normal and spec color maps). i brighten up the Night scene a bit for the Preview here (because it's a small picture). most of the textures are greyscale, so you can change the color of them with the Diffuse Color.
I don't use the BGE very often, so i am sorry i cant help you. I can only tell you i dont built it for BGE and it also crashes when i try to run it in BGE :-)
Amazing how the scene looks so different in the three renders. I'm really glad you posted this.
The model is just what I needed, but it's missing a couple of the textures. I've been exporting it in .obj format for a game I'm working on for school. And when I load its giving me an exception because one of the tree textures is missing along with one of the fence textures
Its nice, but when I try to use in bge it crashes for some reason? is it not compatible?
