What it does

Turns a creative-direction matrix into an exhaustive variant grid. You define styles on one axis and subjects on the other; it renders every combination, stores each cell, and assembles a single contact-sheet gallery so a creative director can scan the whole space and pick winners in one view.

When to use it

Run it during early concepting when you want to explore the full creative space for a campaign before committing, rather than guessing at a few directions. It is the fastest way to put a complete style-by-subject grid in front of a reviewer for a go/no-go.

How it works

  1. 1An operator runs the workflow manually with a style list and a subject list.
  2. 2The workflow computes the full cross-product of style x subject combinations.
  3. 3generate-image renders an image for every matrix cell.
  4. 4Each render is uploaded to R2 under a matrix-cell key.
  5. 5The workflow assembles a contact-sheet gallery document and writes it to Google Drive.
  6. 6It outputs the shareable Drive gallery link for creative-director sign-off.
