Hangar Bay — COG Factory

Q. Does a real SKY surface (surf_flags 0x200) open a room to the outside, and can one big volume read as scale rather than as emptiness?

Yes — the sprint's most reusable single finding. A surface flagged 0x200 with the stock 00starry.mat renders as the sky box: a real starfield through the bay mouth, with nothing modelled beyond it.

Installing it

P35.GOB is a level. Unzip it and drop the GOB into your episode folder.
Pick it from the episode list.

The GOB carries its own level, models, and materials.

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 P35.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.
