VMEX

Valve Map Extractor (VMEX) is a decompiler for Source engine maps. It converts BSP format files back into VMF format maps that can be loaded into Hammer. Since version 0.98g it supports all of Valve's games up to Left 4 Dead.

The Ship

To decompile maps for The Ship, download the modified version: VMEX (v0.98e) here.

Left 4 Dead

A modified version of vmex was created for decompiling Left 4 Dead maps by TerabyteDragon with permission by the original author. This modification resolves an issue with static props (specifically how large the entries are in the BSP file). This version can be downloaded from the link below. Note: This version of vmex is NOT guaranteed to work with maps from any other game.

Left 4 Dead 2

A pre-processor to modify Left 4 Dead 2 BSPs to be decompilable by VMEX written by Omnicoder can be downloaded below.
