Neon Undercity — COG Factory

Q. Can a reference photo's LIGHTING CHARACTER — coloured neon pools in a dark alley network — be carried into the engine by a bridge-side bake alone?

No — and that is the result. DF2 per-vertex light is INTENSITY ONLY; the colour has to come from the sector's TINT, and tint only colours what the sector's light level already illuminates. The sprint's control level, and the one that taught the most.

Installing it

Unzip it.
Drop the .GOB into the episode folder of a Jedi Knight install — the one that already has JK1.GOB in it.
Pick it from the episode list. On a libretro frontend, load the .GOB itself as content.

The GOB carries its own level, cogs, materials and sounds and reads the stock resource/ for everything else. There is no retail game data in the zip.

These are living projects, not finished releases. A level is rebuilt whenever something is learned — a lighting rule, a texture orientation, a whole detail pass — and it keeps its filename through all of it. The build number is how to tell which one you have: it is printed in the readme inside every zip, and it only moves when the level's bytes actually change.

INSTALLATION
------------------------------------------------------------------------
Drop P33.GOB into the `episode` folder of a Jedi Knight install (the one
that already has JK1.GOB in it) and pick it from the episode list.
Nothing else needs to change: the GOB carries its own level, cogs,
materials and sounds, and reads the stock resource/ for everything else.

On a libretro frontend, point the core at the GOB itself. It needs a
folder beside it holding `resource/` from a real install -- that is
where the retail data lives and none of it is in here.
