Bmodel

A bmodel (short for brush model) is a model made out of BSP brushes. These are normally called from within the currently loaded BSP map file. Each bmodel uses its own BSP tree; there is a bmodel for worldspawn, as well as bmodels for each brush entity.

With the exception of the bmodel used by worldspawn, are called from an entity using *# in the model KV, wherein # is a number representing the location of the bmodel in the BSP file. Worldspawn always uses bmodel 0.

In Quake and GoldSrc, any entity can use bmodels from a separate BSP file from the currently loaded map. If a bmodel is loaded from a separate BSP separate, the worldspawn bmodel will be used.

Note:All point entities can use MDLs, SPRs, and separate BSP models interchangeably.

Important:Bmodels contained in separate BSPs are usually fullbright, because they cannot inherit lighting info from the world.

Tip:Use ericw-tools and compile with -dirtdebug to apply some generic ambient occlusion to the standalone BSP model's lightmaps, improving visibility.

In Source, only bmodels built into the current map can be used.^[confirm]
