Control Room — COG Factory

Q. Can ANGLED, non-axis-aligned surfaces — raked console banks and a canted viewport — be built and still get a collide box that fits?

Yes, and the box survives detailing — 6 surfaces became 99 in the same sector and it still clears every one of their planes, at scale 0.727. The detail pass then found the room was black for a reason nobody had checked: sector ambient does not light a surface at all (sithRender.c:2046 vs :2718 for a thing), so the declared ambient=(0.24,0.30,0.36) lit the console meshes and nothing else, while three lights of range 0.55 in a room with a 0.803 half-diagonal reached 4 of 12 vertices. 32 of 36 samples were literally the bake floor, 0.120 — reproduced offline to four decimals before anything was changed. tessellate had also cut nothing, silently, because it only proposes lines the sector's vertices already occupy, so the floor was one quad and a pool of light on it was unrepresentable rather than dim. And the windows were "very tiled" twice over: a texture painting its own 4×4 pane grid, tiled 2.90 × 1.47, is 12 × 6 panes — fixed by taking the grid out of the art and cleaving real mullions into the leaning wall, which band_strip cannot touch and raw cleave_surface does in one call. Median vertex light .120 → .264 over 444 samples; room void .3007 → .0708.

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 P39.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.
