If there is a leak in the level, only standard lighting will be computed - radiosity will not be simulated, resulting in faker/harsher lighting. This program computes the lighting of the map, including pseudo- radiosity for Source maps, resulting in more natural-looking lighting. *Finally, the level passes through the "rad" program. Since the Source engine uses portal based rendering to determine what is visible at any given time, this program creates the portals by dividing the map into convex regions with visibility data, like Quake-based engines do at a per-polygon level. *Second, the level passes through the "vis" (Visible Information Set) processor, which determines what polygons are rendered and what lights appear where. It also places all entities where they should go based on the level design file (.vmf file). This program uses the brushes to create the architecture of the level. *First, a level is passed through the "bsp" program. The following list is largely true for both formats, but is intended as a reference for Source levels. Valve includes compiling tools with the " Source SDK" - "vbsp", "vvis", and "vrad". It originated because of Half-Life's reliance on the Quake engine, and has remained as a result. vmf format is a simple file that contains all the information about a level in a format vaguely similar to an XML file. Before this, it saved a level file in the binary, proprietary ".rmf" or text-based, human-readable ".map format." The. Valve Hammer Editor version 4.0 saves a level file in the ".vmf" format by default. Many level designers who work with both Source and GoldSrc games usually keep an install of 3.5 to avoid using unsupported features in a GoldSrc game. However, some features of version 4 and above, such as displacement maps, are not compatible with GoldSrc. Sets of simpler primitives can be used in older GoldSrc games. Prior to the release of Source, Hammer used only brushes (blocks) called primitives. The current version supports both Source and GoldSrc, and can only be accessed via a free download of the Source SDK.

Versions prior to 4 supported exclusively Goldsrc, Source's predecessor. Old versions of Worldcraft also supported " Quake" and " Quake II". Valve Hammer Editor, formerly known as Worldcraft and now commonly called Hammer, is Valve Software's map creation program for their game engine, Source.
