An urban industrial setting requires a lot of buildings, and that's perfectly fine because I really enjoy kitbashing. Many of the buildings went through multiple revisions as I worked to achieve the right look. I frequently posed partially-assembled shells to get a sense of how everything might fit together, and to help me decide where I might need to make changes in the arrangement of streets and so forth.
The process actually began before tracklaying; above is an early test from May 2013. Compare what with another test done two months later; many buildings were changed and some streets were rearranged:
Additional changes followed, although they gradually became more subtle and detail-oriented. The old JCIR website had individual pages devoted to each and every structure, with blow-by-blow accounts of how they were built. Because I doubt there's much value in recycling such a finely-grained look at a lot of old stuff, I'll simply highlight a few of the more noteworthy projects. In particular, you'll see how reference photos influenced much of my work.
