Import files and assets

9min

Learn how 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

You can upload the following file types:

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

Recommended file size

For optimal performance, use files under 300 MB. Larger files may impact performance both while building in the Editor and when users access your experience online.

Importing files into your project

All files and assets are managed in the Assets tab, where you can find two categories available to you:

  • Assets: Contains all the prefabricated and optimized assets that come with the Studio.
  • Files: Holds your uploaded files. Allows both single-file and folder uploads for glTF formats.

Here is where you can find these categories:

How to import files

You can import your own files into the platform from both the Files and Assets categories, with the Upload Files or Upload Folder options, or by dragging and dropping files into the Editor.

Uploaded files appear inside the Files category and inside My Assets within the Assets category.

Alternatively, you can also drag and drop files directly into the Viewport or Hierarchy to place them into your scene.

Dragging files into the Viewport

Dragging files directly into the Viewport adds them to your scene at the specified location. These files also appear in the Hierarchy and in the Files category of the Assets tab.

Dragging files into the Hierarchy

Dragging files into the Hierarchy places them into the scene at the default coordinates (0,0,0). These files also appear in the Viewport and the Files category of the Assets tab.

Specific format importing guides

While the iR Engine supports a variety of formats, follow these best practices for specific file types.

Importing glTF files

To import a complete glTF model that consists of multiple files, ensure all associated files (textures, materials, etc.) are stored in the same folder on your device.

💡 Tip: Convert GLB to glTF

Use the GLB Converter tool from Convert 3D to convert GLB files into glTF format for optimal performance.

To upload a glTF folder:

1

Open the Assets tab in the Editor.

2

Open the Files category.

3

Click Upload Folder.

Uploading folders feature

Always use the Upload Folder button in the Assets tab to import multiple files for an asset, such as a glTF model.
