BSP (file)

File storing level geometry and objects for Quake engine and all of it's successors (Id tech 2, Id Tech 3, Goldsrc engine, Source engine, etc.).

BSP is not suited for direct editing. It get builded from a MAP file. The process of building is called compilation. Compilation have several stages:

• BSP - first stage, map geometry is converted to BSP tree, all level structures are created.
• VIS - cluster-to-cluster visibility being calculated.
• LIGHT - static lighting (lightmap, lightgrid) being generated.

For each game engine, BSP file version and structure is different.

Darkplaces engine can load following BSP file versions:

• Quake BSP
• Half-Life BSP
• Quake 3 BSP

Blood Omnicide is using Quake 3 BSP for all levels.
