Black spot with start.lit

[Baker]

I have discovered the start.lit that has been around for ages shows a black square near the Episode 1 teleporter in FitzQuake 0.85.

How likely is it that this is a flaw in the start.lit file versus the engine?

I ask because MH has some notes about corrupt lit files in his engine and I just don't see anything in the lightmap loader that could be wrong.

If it in the engine issue category, would this be doing all the lightmaps except 1 or any suggestions from anyone on how to narrow down what could be doing this?

a) Could this be a dlights issue (nope, checked) or a lightstyle change issue? (This 2nd one sounds like something MH talked about. Something about the default lightstyle and the new one being the same not triggering a refresh of something or rather .... I don't recall the details of it obviously)

Must be an engine bug of some sort.

Tried FTE and it looks absolutely fine.

fte, fuhquake, and presumably also ezquake+fodquake normalize light intensities to match the bsp's original lighting.
this does two things:
1: 'fixes' the dodgy lit files that were around in the qw scene at the time (you can still get strange colours, just the intensity is consistant with how the map always was).
2: ensures that you cannot make the map fullbright by just filling up the lit file with the value 255, and for this reason there is no setting to disable lit normalisation (although a value of 32 or so would mean players and fullbright skins would be *really* visible).

replacement .lit files that have a subtle lighting algorithm difference between the bsp's light and the relight process can result in surfaces which should receive light in the lit file, but where that lightstyle does not affect that surface. The relight tool will apply light to the neighbouring surfaces that can receive light, but the surface which doesn't have that lightstyle allocated to it cannot receive ANY light... either the relight tool allocates it to the wrong lightstyle or just drops that light entirely.

I've put in "averaging" against the in bsp light data and it limits the issue. Maybe I'll fix start.lit, but at least I know what issue is now. The .lit file.

Drives me a bit crazy that a 10 year old file would have such an issue go unnoticed, but I guess it happens ...
