The light maps in IdleTime are extremely bad. In fact I'm not even sure you could call them light maps. Basically they just store the shadows. The UV densaty is a joke, there is no ambient occlusion, no bounce lighting, no nothing.
So whats this got to do with source control? Looking at the above screen shot I decided that I should fix the light maps. Long story short I can't find the code for the light mapper.
Obviously if you have more then one coder on a project source control makes total sence. But why use source control when there is only one programmer?
Lesson #3 for old me:
Always use source control. A part from the obvious, history. Having history will make your code a lot cleaner. I found that when making a big change to the code I would just comment out the old code and add the new code in. This gets very messy very fast. I've been using Perforce at home, they have a 2 (maybe 3) user version for free.
