One shoe, modelled once, taken to a full drop.
Solvei and its running shoe Tern are invented. The shoe was built as one 3D model; every packshot, campaign image, loop and product page on this page derives from it.
- For
- Footwear designers and e-commerce leads at sportswear brands.
- What
- One running shoe in 8 colorways and 4 uppers, 5 campaign worlds with a hero loop each, 32 product pages and a 3D view.
- Scenario
- An agent with the Scenario MCP ran 176 calls across 18 models, 6,414 CU in all: the 3D model, the material finishes, the worlds, the loops and the film.
Build the drop
Pick a colorway and an upper, then see the same shoe as a packshot, in 3D, in five worlds or as its product page.

Four uppers you can tell apart
Same last, same colorway, four surfaces. Each close-up is cut from the finished image of that upper, so what you see is what the packshot carries.

One hero loop per world. Each starts and ends on the finished campaign image, so it plays without a seam; only the air moves.
Every world also exists in all eight colorways (40 images): pick one in Build the drop.





Seedance 2.5, first frame and last frame the campaign still, 6 seconds, no sound. A low-resolution preview of all five came first; one desert take went back for a clearer sky.

One job failed (MAI Image 2.5 Pro Edit, 44 CU); its cost is counted. Base renders are three.js real-time renders of the one 3D model, made in code, no Scenario call. The film was cut at 6,060 CU, before the relight of the track hero (5 calls, 354 CU).
