VMAP stands for Valve Map, and it is the main map file extension used by Source 2 Hammer. The file itself is just a DMX file under binary encoding version 4, however Hammer can export an ASCII-encoded vmap by clicking "Save Copy As Text".

Some key differences with preceding formats:

	Source	Source 2
Geometry uncompiled	Brushes in Valve Map Format	Meshes in half-edge format
Geometry partitioning	Node and leaf lump / BSP	.vwnod_c file / octree
Geometry compiled	Face lump	.vmdl_c files
Visibility compiled	Visibility lump	.vvis_c file
Physics compiled	Physics lump	.vphys_c file
Entities compiled	Entity lump	.vents_c file

Compiled VMAP

VMAP_C stands for Valve Map Compiled, and is the main map file extension used to load maps in Source 2. The .vmap_c file is used to refer to various map dependencies (including vwrld, vwnod, vvis, vphys, vents, vtex, vmdl, vrman; usually residing in maps/<mapname>/) as well as other external assets used in the map.

This file along with its main dependencies usually get bundled together into a single VPK file, the latter of which serves similarly to the .bsp. Since lumps are separate files, they get packed and live next to other assets in the VPK. This makes post-compile addons much more convenient than in Source (see Patching EP1 levels vs. HL:A Map Extensions).

Its usefulness to the engine seems questionable as <code><mapname>/world.vrman_c</code> also refers to all the same vital dependencies.<sup>?</sup>

-This file along with its main dependencies usually get bundled together into a single [[VPK|.vpk]] file, serving similarily to a .bsp. Compared to the [[Source BSP File Format|source BSP format]], you can see that lumps are now separate files, and so the [[Source BSP File Format#Pakfile|Pakfile lump]] idea was extended to also hold all these lumps (as files inside <code>maps/<mapname>/</code>). This makes post-compile addons much more convenient ''(see [[Patching levels with lump files|Patching EP1 levels]] vs. [[Half-Life: Alyx Workshop Tools/Level Design/Map Extensions|HL:A Map Extensions]])''.
