Half-life BSP file-format

Recommended Posts

Does anyone know anything about the Half-life BSP file-format? I found a good document on the Quake2 format, but apparently there are some differences between them.

Half-Life uses a modified Quake1 Engine NOT Quake2. Go for a look at the Quake1 BSP format (version 36... I think?) the main difference is that textures are stored externally.

The Quake1 Engine is also open source so info on it''s BSP format should be easy to find.

Also, get the Half-Life SDK and/or the source code for Zoner''s Half-Life tools in addition to the Quake 1 tools. They''ll tell you everything you''d ever want to know about the HL .bsp format.

Quake 1 BSP version is 29, Halflife is 30. The Halflife BSP format supports external textures, as well as internal textures. The lightmaps are 24bit colour instead of 8bit greyscale. The compile tools recognize origin brushes, etc.

The general BSP format is almost identical tho.
