Importing 3D Assets

You can download Qt Bridge from the Qt Marketplace. It enables you to import files you created using 3D graphics applications and stored in several widely-used formats, such as .blend, .dae, .fbx, .glb, .gltf, .obj, .uia, or .uip. For a list of formats supported by each Qt Quick 3D version, see the module documentation.

For more information about exporting 3D graphics, see Exporting 3D Assets.

To import 3D assets to Qt Design Studio projects:

  1. Drag-and-drop an external file containing the 3D asset from, for example, File Explorer (on Windows), to 3D Editor.
  2. In the 3D Scene Options tab, select options for importing the file.
  3. Select Import to import the 3D graphics file.
  4. When the import is done, select Close.

The 3D asset you dragged-and-dropped to 3D Editor has now been added to your scene, and you can see it in the 3D Editor view and in Navigator. It is also available in Library > Components > My 3D Components.

Alternatively, you can initiate the import dialog from the Library view:

  1. In the Design mode, select Library > Assets > .
  2. Select 3D Assets in the dropdown menu to filter 3D graphics files.
  3. Select a file to import, and then select Open.
  4. In the 3D Scene Options tab, select options for importing the file.
  5. Select Import to import the 3D graphics file.
  6. When the import is done, select Close.

The 3D asset now appears in Library > Components > My 3D Components. You can add it to the scene by drag-and-dropping it to 3D Editor.

During the import, you can optimize the files for Qt Design Studio. You can remove components from meshes to reduce the cache size, find and fix issues in the files, optimize graphs and meshes, and so on. The available options depend on whether you are importing files that you created with Qt 3D Studio or with other 3D graphics tools. See the tooltips in the options dialog for more information about a particular option.

The 3D asset you added to the project now appears in Library > Components > My 3D Components. You can add it to your UI by dragging-and-dropping it to 3D Editor.
