Those of you working with lightmaps a lot in your levels... what sort of lightmap resolution do you think is an acceptable minimum? I mean, in terms of pixels per VIRTUAL METRE. That is, if you are in a virtual room 6 metres by 6 metres, normal height, how many pixels across per wall do you think would look okay? I'm talking minimums before it looks really shoddy. What sort of resolutions are you working at, on average?

Or is that a REALLY vague question?
