The Doom3 single player maps contain loads of really quite spectacular-looking machinery, dynamic lights, Screens, Panels and Trims. Trouble is, when you load them up in Radiant, it's almost impossible to get an idea of how they were constructed because the grid is just full of too many lines (especially side and front views).
The solution was to strip the component pieces out so they could be viewed without this 'pollution'. I spent many hours going through the id maps and isolating machinery and scenery. All have been dragged to the 'Z point' for maximum ease when mapping. In-Editor Screenshots have also been included to save even more time. In addition, I've made a few of my own and thrown them in as a gift :-)
This originally started out as a personal time-saving measure, but the whole thing generated a huge amount of interest that completely exceeded my expectations. It is for this reason that I decided to go back and do things properly :-)
