What you get
- A creative method with its instructions and supporting source files.
Setup and requirements
- Follow the included guide to bind your inputs and select the appropriate runtime.
Things to know
- Staging runs on a handful of subjects (products, a logo, hair, glass, two clips); not a matting bake-off.
- Shadows are removed; glass keeps the old background colour; every salient subject is kept (no prompt).
- Production needs the -prd variants published and a T4 graph-execution price (owner).
