Cantina — COG Factory

Q. Can a level be carried mostly by THINGS — furniture, fittings, a bar — rather than by its geometry?

Yes — and the detail pass found the sprint's worst shared bug. Every wall texture in every level is upside down: v indexes a MAT's row, row 0 is the top, and jklib.planar_uv makes v grow upward. This bar's painted bottles hung neck-down. 32 of 32 drawn surfaces are upright now, all four trim bands are in service where only one was, and the bottles are geometry — sixteen of them, each taking its glass colour from a different swatch of the rack texture, for no new art.

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 P36.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.
