+ QtMeshEditor registers as a document handler on macOS, Windows, and Linux. After install, + double-click supported models or use your file manager's Open With menu. + Launching with a file path loads it in the GUI; if the app is already running, the existing + window is focused and the new file is imported (single-instance). +
+
+ The editor can import many formats via drag-and-drop or QtMeshEditor path/to/model.ext,
+ including .vrm, .3ds, and additional Assimp types beyond the OS registration
+ sets below.
+
.fbx, .glb/.gltf, .obj,
+ .dae, .stl, .ply, .vrm, .3ds,
+ .scene.glb/.scene.gltf, .mesh, .rsd, .tmd
+ via CFBundleDocumentTypes; Homebrew cask runs lsregister after install..fbx, .glb, .gltf, .obj,
+ .dae, .stl, .ply, .mesh, .rsd, .tmd
+ added to OpenWithProgids (not default-app takeover). Inno Setup installer on release;
+ portable ZIP includes bin/scripts/register-windows-file-associations.ps1..fbx, .glb/.gltf, .obj,
+ .dae, .stl, .ply, .mesh, .rsd, .tmd,
+ .scene.glb/.scene.gltf via .desktop + XDG MIME in
+ .deb and Snap; postinstall runs update-mime-database and
+ update-desktop-database.
+ CLI mode is unchanged: qtmesh info model.fbx still runs headless. Only
+ QtMeshEditor model.fbx (or OS open-with) enters GUI-with-file mode.
