When you first run a map and are done generating, relaunch the game with the same map. There is a bug on first run that causes problems!
This also includes a SDK source code release.
This is the first binary release of IcedTech. To run, extract these files into your Doom 3 folder. In your Doom 3 base folder, extract Pak003 into your base folder(so you have a sound folder in base). Then open Convert.Bat. and fix the paths so it matches were you have everything extracted. Do NOT have in a folder with spaces! Run convert.bat. Once that job finishes then execute run.bat to run IcedTech.
You can access the editor with +editor as well or editor command in game.
