# Create Material Asset Group

> Creates a TokenLab Seedance material asset group for the current organization.

Creates a TokenLab Seedance material asset group for the current organization.

Use a material group when you want to organize reusable Seedance 2.0 assets by library type. Groups are scoped to the authenticated organization and cannot be used across accounts.

Most integrations can skip this call and omit `group_id` when creating an asset. TokenLab will use or create the organization default group for the selected `library_type`.

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

Use the returned `id` as `group_id` or `material_group_id` when calling [Create Material Asset](/api-reference/video/create-material-asset).
