Import files and assets

Learn to import files and assets into your project so you can use them in your scenes.

Formats supported and size limit

For optimal performance within the iR Engine, consider these guidelines when importing assets:

List of supported formats

Supported file formats include:

• 3D model formats: .glb and .gltf (with .bin and .ktx2)
  • The Studio does not support .fbx
• Image formats: .png, .tiff, .jpg, .gif .jpeg, and .ktx2
• Audio formats: .mp3, .mpeg, .m4a, .wav
• Video formats: .mp4, .mkv, .avi

Recommended file size

For optimal performance, use files under 300 MB. Files over this size affect the performance of your experience both when building it in the Studio and when users access it on the web.

Import files into your project

Import assets into your scene via the Files tab. To do this, you can drag and drop or use the Upload Files and Upload Folder buttons.

These actions place the file into your folder within the Files tab and make it available in the Assets tab as well.

If you drag and drop your files, you can place them directly in the Files tab, the Viewport, or the Hierarchy. These options provide their own benefits; see the following sections to know more.

Danger

Do not upload assets using the Assets tab or the Hamburger menu (☰). The Assets panel is being reworked and will provide an improved experience in future releases.

Importing files directly into the Viewport

To upload files directly into your scene, you can drag and drop them into a location in the Viewport. Doing this also loads them into your scene Hierarchy. You can view imported assets in the assets folder of the Files Tab.

Importing files directly into the Hierarchy

To upload files directly into your scene, you can drag and drop them into the Hierarchy. Doing this also loads them into the Viewport at (0,0,0). You can view imported assets in the assets folder of the Files Tab.

Specific format importing guides

While the iR Engine supports a variety of formats, here are some additional guidelines for specific types:

Importing glTF files

To import a complete glTF model that consists of multiple files, you must first combine all associated files (textures, materials, etc.) into a single folder on your device.

To upload your folder:

1. Navigate to the Files tab in the Studio.
2. Click the Upload Folder button.
3. Select the folder containing all your glTF model files for upload.

Uploading folders

The iR Engine does not support uploading folders using single file upload methods. Always use the Upload Folder button in the Files tab to import multiple files belonging to a single asset, like in the case of gLTF files.

Next steps

Now that your files are ready to use in your project, you can proceed to load assets into your scenes to begin building your experience.
