🎬 Filmmaking & Animation · 3D prop modeling

VertexFlow · x402

A headless 3D mesh repository where animators pay 0.01 USDC per asset 'pull' or render-call. Instead of clunky licensing contracts, every import into a scene (Blender, Unreal, or Unity) triggers a micropayment to the creator via HTS transfer. Creators stream revenue in real-time as their props are used in production, while studios avoid massive upfront library fees.

The primitive.

full primer →

Access to the 3D prop modeling engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so filmmakers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy shifting from 'Minting' to 'Metering,' we turn static assets into active revenue streams. Using x402 allows for per-object or per-render-instance billing, which is the natural economic unit for high-volume 3D production.
