Based on suggestions from my friends Adrian and Dean, I redid my sci-fi pre-fab buildings using textured paint. The buildings in the above image were painted with ColorTex's "Quarry," for a gray, city-like environment.
As I mentioned in my earlier post, these structures were made from two models of Sterilite trays:
#1605 (6 1/4" x 5" x 2 1/8"
#1606 (9 5/8" x 6 1/4" x 2 1/8")
I wanted to diversify the color-scheme a bit, so for a desert or frontier environment, I chose two colors. The first was "Desert Bisque" by Rustoleum:
And the second frontier color was "Santa Fe Sand" by Volspar:
For all the buildings, I used black construction paper for the windows. I chose black for versatility, so the windows can be considered darkened, tinted or completely blown-out.
I downloaded images of blast doors from a gaming/miniature website. At this time I'm afraid I can't remember, or find, what that site is. When I do, I'll be sure to post it to give the creator(s) proper credit.
I may add some more details to these buildings, like access hatches to the roofs, or antenna arrays, etc. But these are wargaming "chrome" and I can use these buildings now as they are.
