Hauksbee, it's looking good but the towers without the flags kind of look like the disneyland castle
The pics look like Disneyland because Disney adopted the early 19th Century architectural style that was popular in Europe. I downloaded about a dozen French chateau pics. They nearly all have towers and roofs like this.
Not sure what you mean by 'frames and built-in textures'. GMAX wants to make every object you create a different color. But, if you right-click a selection, you can get a Menu Box. Click on 'Properties' and it will take you there. There's a place that shows the color of the object. Right click on that and you'll get a (256?) color palette. Pick whatever you want.
I'll get to work on texturing.
RAF_Lou, what kind of objects will you need for your airfield?
EDIT: Just saw your latest post, Lou. Let me dig out some texture samples and we'll go from there. I think Robert and I can hammer out a couple of walls.
