Uploading Custom Assets

Uploading Custom Assets

Storyboarder supports uploading your own custom assets, allowing you to bring in characters, objects, images, poses, and more to use across your Editor Files.

How to Upload

You can upload assets from the Upload button in the 3D View toolbar within the Editor

Multiple files can be uploaded at the same time, with the exception of character files which must be uploaded one at a time.

Supported File Types

Asset TypeSupported Formats
3D Objects.glb, .gltf
Characters.vrm
Poses.vrma
Images.png, .jpg
Compressed.zip

File Size & Limitations

3D Models - there is a maximum file size for 3D models, but uploaded models are automatically resized if they exceed it.

Images - maximum resolution of 2048 x 2048px. Images larger than this should be resized before uploading.

Finding Your Uploaded Assets

Once uploaded, assets appear in your My Assets library and are accessible from the relevant asset browsers in the Editor. Uploaded assets are available across all of your Editor Files.

To keep things organized, you can group related assets into Collections - named folders within My Assets that help you keep characters, props, and images for a specific project together in one place.

Sharing Uploaded Assets

If you'd like to share an asset you've uploaded with the broader Sumugi community, you can submit it to the Asset Marketplace directly from My Assets.

Tips

Use .glb for 3D objects where possible. GLB is a compact binary format that keeps textures bundled within a single file, making it simpler to manage and upload than GLTF which may require separate texture files.

Use Collections to stay organized. If you're working on multiple projects, grouping your assets into named Collections makes it much faster to find what you need when switching between Editor Files.
