Yea it fixed the light issue - thanks! I still had a really hard time though unfortunately - again it might just be me but if you can interact with something a widget popping up to tell you what to press would be massively useful (eg. [F]) - I think that and maybe making it slightly easier at the start would be great.
I really like the effect of seeing what is in front of you in the camera viewfinder though, very cool effect!
