About​

This section describes the extensions that are found in the game files and the SDK.

General​

ExtensionDescription
*.log Anomaly Modding BookEvent log. It contains records of program start, operation and termination
*.pdb Anomaly Modding Book
*.scop Anomaly Modding BookSave file
*.scoc Anomaly Modding BookSave file
*.xrdemo Anomaly Modding BookRecording camera flyover (demo). Created in the game with a console command Anomaly Modding Book.
*.ogm Anomaly Modding BookThe video format used by the game engine.
*.ogg Anomaly Modding BookThe sound format used by the game engine.

Configuration and script files​

ExtensionDescription
*.ltx Anomaly Modding BookConfiguration file, custom ini-like format
*.script Anomaly Modding BookGame script
*.xml Anomaly Modding BookCarry in text format data related to in-game text, UI element placement, and characters and information within the game world
*.seq Anomaly Modding BookText file containing a description of the frame sequence in the 2D animation

AI​

ExtensionDescription
*.efd Anomaly Modding BookTable of AI heuristic parameters, contains constants for fine-tuning A-Life. They are used as input parameters in scripts

Textures​

ExtensionDescription
*.bump Anomaly Modding BookNormal map in A(BGR) format
*.bump# Anomaly Modding BookFile that fixes DXT compression errors in *_bump.dds Anomaly Modding Book
*.dds Anomaly Modding BookGraphic file used by DirectX to store textures
*_detail_map.dds Anomaly Modding BookSame as a regular *.dds Anomaly Modding Book texture, needed as an extra map in a *.thm Anomaly Modding Book
*.tga Anomaly Modding BookA bitmap graphics format with support for color depth of 1-32 bits per pixel, alpha channels, and RLE compression. Used as a source format.
*.thm Anomaly Modding BookThey are used to set the parameters of textures - bump, detail, and more.

Shaders​

ExtensionDescription
*.cs Anomaly Modding BookCompute shader
*.gs Anomaly Modding BookGeometry shader
*.ds Anomaly Modding BookDomain shader
*.hs Anomaly Modding BookHull shader
*.vs Anomaly Modding BookVertex shader
*.ps Anomaly Modding BookPixel shader
*.s Anomaly Modding BookScript shader. Lua version of engine blenders

Postprocess​

ExtensionDescription
*.ppe Anomaly Modding BookPostprocess file format. Color-noise effects of the actor's screen

Models​

ExtensionDescription
*.dm Anomaly Modding BookEffect of a dynamic weather environment (e.g., rain or lightning)
*.object Anomaly Modding BookThese files are intended for the X-Ray SDK to store 3D content in its original, uncompressed, lossless form. They are source files that store information before compilation into other game compressed formats.
*.ogf Anomaly Modding BookCompiled object
*.bones Anomaly Modding BookSkeleton bone data files
bone_parts.* Anomaly Modding BookBone part description file for an object/NPC
*.group Anomaly Modding BookObject groups

Animations​

ExtensionDescription
*.anm Anomaly Modding BookA set of coordinates, which works as an animation of the actor's camera movement. It is also used for anomalies, which need to be given a path.
*.skl Anomaly Modding BookSkeletal animation
*.skls Anomaly Modding BookSkeletal animations(.skl) in a container
*.omf Anomaly Modding BookA specialized S.T.A.L.K.E.R. game format containing animations. This is a separate dedicated file used in conjunction with *.ogf Anomaly Modding Book models. Was created in order to optimize process when some different models use the same list of animations.

Archives and Resource Packages​

ExtensionDescription
*.db Anomaly Modding Bookarchive of game resources. Used in late builds and the final version of the game, has several options (db."number", db."letter").
*.xr Anomaly Modding Bookresource library. Contains resources such as particles, Engine Shaders, Compile Shaders Anomaly Modding Book. in a packed format.

Game level​

ExtensionDescription
*.err Anomaly Modding BookContains information about geometry errors during level compilation
level Anomaly Modding BookFile with general information about the game location (light sources, object names, texture and shader names, sectors and portals). Created during compilation
*.prj Anomaly Modding BookLevel precompilation file
*.ai Anomaly Modding BookAI location grid. Created during compilation
*.cform Anomaly Modding BookGeometry for calculating collisions. Calculated by the level compiler. Contains a solid map structure. All tangible objects with materials live here. Because of this, the game knows with what sound and property objects should react when they are hit by bullets or walked on
*.details Anomaly Modding BookDetail Objects (grass, cigarette butts, construction debris) on the level. Created through LevelEditor SDK at compile time.
*.env_mod Anomaly Modding Booklocal environment modifiers (environment), set areas on the location with lighting different from the main weather cycle.
*.fog_vol Anomaly Modding BookVolumetric fog
*.game Anomaly Modding BookCoordinates of the player's spawn in the multiplayer game. Outdated file.
*.geom Anomaly Modding BookContains vertices (position, normals, texture coordinates, etc.), indices, and information for smooth geometry detail.
*.geomx Anomaly Modding BookIt contains only geometry. In the renderer it is used in the shadow rendering passes, due to the fact that there is less information - loading data into the buffers - faster.
*.gtc Anomaly Modding BookCross table of correspondence between the location graph and the AI grid. Created during compilation
*.hom Anomaly Modding BookMapping of hierarchical cutoffs
*.level Anomaly Modding BookList of SDK scene objects
*.lights Anomaly Modding BookLight sources for xrLC
*.ps_static Anomaly Modding BookParticle systems. Flies, steam from pipes, etc.
*.graph Anomaly Modding BookGlobal graph of AI navigation. Used, among other things, for moving AI objects outside the active level.
*.spawn Anomaly Modding BookA file storing spawn data.
*.snd_env Anomaly Modding BookVolumetric sound sources.
*.snd_static Anomaly Modding BookStatic point sources of sound. Sound of flies, etc.
*.som Anomaly Modding BookGeometry for calculating sound propagation.
*.wallmarks Anomaly Modding BookDecals. Bloodstains, faction emblems on walls, etc. Used for the compiled level.
*.part Anomaly Modding BookScene objects
