BSP sekai (BSP world) is a level converter for Quake 3's BSP format and games based on it. It is based on the BSP loaders in the Spearmint engine.
This is alpha software, there are many issues of things not properly change or removed when converting to other BSP formats. The only supported conversion is NSCO maps (Q3 with modified surface/content bits) to Enemy Territory BSP format.
bspsekai <conversion> <input-BSP> <format> <output-BSP>
BSP sekai - v0.2
Convert a BSP for use on a different engine
BSP conversion can lose data, keep the original BSP!
<conversion> specifies how surface and content flags are remapped.
Conversion list:
none - No conversion.
nsco2et - Convert Navy SEALS: Covert Operation surface/content flags to ET values.
et2nsco - Convert ET surface/content flags to Navy SEALS: Covert Operation values.
The format of <input-BSP> is automatically determined from the file.

Quake 3 (including pre-releases formats), RTCW, ET, EF, EF2, FAKK, Alice, Dark Salvation, MOHAA, SoF2, JK2, JA, Iron-Grid: Warlord
<format> is used to determine output BSP format.

Quake 3 BSP format is also used by Elite Force, Tremulous, Smokin' Guns, World of Padman, Turtle Arena, and other games. Soldier of Fortune 2 BSP format is also used by Jedi Knight 2: Jedi Outcast and Jedi Knight: Jedi Academy.
