I've spent the last few months working on one of the most ambitious projects I've ever started.  It's been slow going and I've learned quite a bit.  Like most projects, I wish I could start over knowing what I know now...

Anyway, I've just been calling it the Urban Texture Atlas Project, because I started making a texture atlas before doing any actual modeling.  Only when I'd collected 75-90% of the little bits and pieces I thought I'd need did I begin the modeling process.  The goal is to have several large modular environment pieces and a number of smaller detail props all sharing the same large texture map.
