index.json is the agent-consumed catalog of color-grade looks. Each entry resolves
on demand — no .cube bodies are committed to the repo.
Each look has:
id, description, tags, intensity — matching + application metadata.scripts/11 filesurl (optional) — a hosted .cube downloaded, validated, and frozen at resolve
time, exactly like bgm/image assets.params (optional) — a deterministic buildCube spec used offline (--local-only)
or as a fallback if the url download/validation fails.An entry needs at least one of url or params; prefer both (CDN url with a params
fallback) so resolution is never blocked on the network.
Generate the .cube (e.g. resolve -t lut --params '{...}' or a graded export).
Upload it to the public CDN origin bucket:
aws s3 cp <id>.cube s3://heygen-public/luts/<id>.cubeIt is then served at https://static.heygen.ai/luts/<id>.cube (CloudFront).
Add an entry to index.json with that url (and ideally a params fallback).
