# Create Material Asset

> Uploads a Seedance material asset into a TokenLab material group.

Uploads a Seedance material asset into a TokenLab material group.

Upload a publicly reachable material URL into the selected Seedance 2.0 material library. The asset is scoped to the authenticated organization.

For most requests, set `library_type` and omit `group_id`; TokenLab will use or create the organization default group for that library type. Pass `group_id` only when you need to upload into a specific material group.

* `aigc_avatar`: virtual-person or avatar materials.
* `liveness_face`: certified real-person materials.

After creation, poll [Get Material Asset](/api-reference/video/get-material-asset) until `status` is `ACTIVE`. Then pass the returned `id` as `material_asset_id`, or include it in `material_asset_ids`, when calling [Create Video](/api-reference/video/create-video).

If the asset becomes `FAILED`, inspect `error_message`, fix the source material, and create a new asset.
