I know I'm going to come off like I've been off planet or some such, but damn, I had no idea that this thing had come along so far.
Last thing I remember was looking at the Quake 3 alpha and Timbo talking about the issues of additive lighting and having to hack Q3 map files.
Very nice work, by the way. The whole standalone engine thing makes the sky the limit on your options. I'm impressed.
