Mascot to boxed collectible mockup with Seedream 4.5 and 3 references

A boxed-collectible mockup (a mascot figure in a toy box on a shelf) takes three references on Seedream 4.5: the mascot, a blank box template and a shelf scene. Each image costs $0.05 on Sume, so five mascots with four takes each come to $1.00.

Seedream 4.5 lists up to 10 references and ratios such as 4:5 and 3:4, but not auto (read 2026-10-03). Use it for concept boards and pitch decks; it does not replace a factory proof.

Writing the prompt around the references

Refer to each reference by its position: image 1 is the mascot, image 2 the box, image 3 the shelf. Say what must be preserved (the mascot's colors and proportions), what the box should say (leave text to your own overlay) and what the light should do. Keep the box template plain so the model does not invent logos.

Four takes are four images at the same per-image price however you batch them, so run the takes as parallel calls and compare the results side by side.

• Generate the box template once and reuse it across mascots to keep the series consistent.
• Add brand names and legal text in your own layout step.
• Use the mockup as a pitch image only; production art needs a real dieline.

The request

Post the three references in the order your prompt names them.
