What is an IQM file?
An IQM file is a 3D model file saved in the Inter-Quake Model (IQM) format, which is designed for use in various video games, such as Cube 2: Sauerbraten and Red Eclipse. IQM files may contain 3D mesh data, animations, bones, and other information the game engine requires to render and animate characters or objects in a game.
More Information
Lee Salzman, also known as "eihrul," developed the IQM format to provide an efficient, modern alternative to older model formats, such as MD5 and MD3. The format is also open and well-documented, encouraging use in community-driven or independent projects.
Developers and modders use IQM files (and related .IQE files) when building or modifying game assets, since the format supports skeletal animation and efficient rendering. While IQM is less common in large commercial engines, it remains a common choice for smaller game engines, hobbyist developers, and open-source gaming communities. Users may export IQM files from various 3D modeling apps, including Blender.
How to open an IQM file
IQM files are not meant to be opened. Instead, IQM files are included in the game's or app's data package (alongside textures, maps, and other assets), and the game engine then loads the IQM file directly to render and animate models during gameplay.
While players typically don't interact with IQM files themselves, modders and developers may open or replace them to change in-game characters, weapons, or objects. For example, you can open IQM files with various tools, such as the IQM model viewer (provided by the format creator) or with Blender, which supports IQM through community plugins and scripts.
