Title: Detecting if a map is lit?
Post by: sk89q on December 10, 2007, 01:51:00 AM

Is it possible to detect if a map is lit?

I would think so- the lightmap is stored in the BSP file, and it would be silly to create an all-fullbright lightmap if the map isn't RAD'd. Or, you should be able to detect the fullbrightnes, at the very least.

But how to do that? I have no clue.

Mapping section.

General Development section. This has very little to do with mapping, just maps themselves.

EDIT: Oh, okay. Whatever. Don't listen to me.

Mapping
Anything related to level design. New map releases go here as well.

I was going to move this to GD...

On topic: I'm looking into it, but if this is for your sexy database, in the meantime  you could decompile the maps and check for the value field (last on line for faces), and maybe make a "possibly lit" or "not lit" depending on whether or not it has those values...

I'm not sure how this fits into the map database at the moment -- there are too few unlit maps to matter. Of course, it could just be put on another 'analysis' page.

By decompiling, do you mean using an external map decompiler? That's not *too* feasible.

Pph. The map format doesn't have anything to do with mapping itself.

Anyway, potential solution to problem. According to this (http://www.gamers.org/dEngine/quake/spec/quake-spec31.html#BL7), says something about 'lightmap' being -1 if there's no lightmap, so it's totally detectable.

Just look at it. If there are changes in the lights and shadows anywhere on the map, then it's lit.

He needs it to be analysed automatically by reading the BSP file.

Fixed.

I should put lightmap detection in the game code and not allow any unlit maps in rotation. :P

That would be just about the best thing ever. Do it for VISing, as well!
