See also:  VMAP, the map file format used in Source 2, which completely replaces the BSP file format used in previous engines.

BSP stands for Binary Space Partitioning.

It can also refer to the following compiled map formats, which have the .BSP file extension:

• BSP30, used by GoldSrc.
  • BSP29, used by Quake, of which GoldSrc's BSP format is based upon
  • BSP2, a modified version of BSP29/BSP30 with expanded limits.
• VBSP, used by Source 1.
  • BSP38, used by Quake II, of which Source 1's BSP format is based upon.
  • rBSP, the modified version of Source 1's BSP format used by Titanfall

Risk of Confusion:rBSP is Respawn Entertainment's modified version of Source's BSP format, whereas RBSP is  Raven Software's modified version of Quake III's BSP format!

The BSP file extension is also used by the various other id Tech 2 and id Tech 3 map file formats, which are not covered by the scope of this wiki.

BSP can also refer to the various map compilers used to calculate Binary Space Partitioning data:

Engine	Original official compiler(s)	Modern third-party compilers
Quake	QBSP	QBSP (ericw-tools)
Quake II	QBSP3	BSP (Q2Tools-220, formerly 4BSP) QBSP (ericw-tools)
GoldSrc	QBSP2	HLBSP (ZHLT, VHLT, and derivatives) QBSP (ericw-tools, experimental)
Source	VBSP	CSTBSP [ Deprecated], Slammin' Compile Tools's VBSP, VBSP++
