[color=#A8A8A8]I think BrianH said they took the tools out, which I took to mean out completely. I would do if building the same codebase across three platforms.[/color]
If they completely took the tools out of the codebase how did they make changes to all the levels?

. You can look at the original gpl doom 3 code your self, there is a macro you can undefine to not build the tool code in your codebase. If you physically took it out of the codebase just to get it to compile your thinking like a first year programmer

, as I mentioned you can block out code without actually take it out. Preprocessor ftw.
