Hah, sorry about the res i'm just having a love affair with my new monitor at the moment. As for the lighting, it's already preset to the recommended values suggested by Valve, but thanks for that anyway. By 'tweaking' i meant literally just toning down the brightness of the lights on the pub and the sun is a bit too glaring when you stand looking into it, so i cut that down in size too.
The project is a SP game for default HL2, involving crazy weapons such as sheep launchers and chav guns (it's british thing - spray someone with some White Lightning cider, their clothes change to burberry and they instantly become an enemy to the other bad guys). It's set in the style of a gameshow in a city that has been walled off to house criminals after prison overcrowding became a problem in the near future.
Whilst the story doesnt matter too much we are just trying to put enough into it (however random) so that our team (5 artists, 5 programmers) has enough to do to earn a decent grade for this final year module. It's also not a project that's likely to be publicly released, as we only have a few months to get the whole thing together, in amongst other, bigger modules, so whilst it may be alright for a university project it won't be too polished compared to other SP mods.
