So, while I'm not about to start another re texturing mod (New Vision was quite enough for me) - I'm curious if anyone who's poked around the source files of HR knows how a retexturing mod might work?

I know it was a pretty awkward process for Invisible War, especially compared to the original Deus Ex - and since HR's engine seems to be even more sealed off than IW's I don't imagine this'd be particularly easy. But I'd still like to have a go at a few choice textures - namely the air vents which seem to be quite low resolution.

So, yeah - anyone got any ideas?
