Look sheets

One generated sheet per character or element is the identity every render reads — and a character without one cannot be cast.

A look sheet is one image — a turnaround of heads and full-body views for a character, a hero sheet for an object, a scene sheet for a place — generated from the reference photos and used as the reference in every render afterwards. It is what keeps a face, an outfit or a product the same across images and clips.

Generating one

Identity tab → Generate. The gauge shows how many references you have: one is not enough, three is enough, four is recommended. With no photo at all, write a description instead.
Review the sheet. Regenerate takes an optional direction ("keep her hair short", "the red version of the jacket") on top of the references.
Accept to make it the identity. The sheet is priced like one image on its engine, shown on the button; the accepted sheet stays in your Library.

The gate

A character or an element (place or object) without an accepted sheet cannot be cast in an image or a clip: the picker says "Create sheet" and the render refuses before charging. The Text tool never needs one. When you add photos newer than the sheet, a Stale badge suggests regenerating.
