Vendor's words
Deprecations, removed on October 31, 2026: the avatar_look_id , character_id and character_type names on character variables (send and read avatar_id ), and the older scenes field on GET /v3/templates/{template_id} (read composition.scenes ). scene_ids is unaffected. Until then both names are accepted and echoed, and scenes keeps its current shape.
