What is an ARM file? An ARM file is a 3D asset created in ArmorPaint, an open-source texture painting application, or by Armory, an open-source 3D game engine that can be added on to Blender. It contains a 3D animation, mesh, model, scene, or other asset. ARM files are created either by saving projects in ArmorPaint or exporting Armory-created games from Blender.

More Information The Armory 3D development team has created multiple 3D modeling and video game creation applications. Two of their most noteworthy apps are ArmorPaint, an app that allows 3D artists to texture, paint, and save 3D models, and Armory, a Blender add-on that game makers can use to make building video games in Blender easier. When an artist saves a project in ArmorPaint, it is saved as an ARM file. Additionally, when a game maker exports an Armory-created game from Blender, Blender produces a number of compiled files related to that game. Some of these files are ARM files. No matter what program created them, ARM files contain 3D models, environments, meshes, scenes, or other assets.
