}Retrieve one material asset and inspect its processing status. The asset can be used for video generation only when
ready is true and status is ACTIVE.
If video generation returns Seedance material asset not found or not accessible, verify that you passed this material asset id, not the material group_id.
project_name isolates resources within the authenticated organization. It defaults to default; use the same case-sensitive value for related groups and assets. Send it in the JSON body for POST/PUT and in the query string for GET/DELETE.
