API README

Hunyuan 3D Smart Topology

Hunyuan 3D Smart Topology occupies a clearly bounded position in a image production pipeline under the route tencent/hunyuan-3d/3.1/smart-topology. It is best evaluated as a named workflow endpoint rather than as a generic substitute for neighboring versions: planners can assign the route to a specific brief, record the chosen revision, and keep approval history tied to one predictable integration surface from intake through delivery.

A practical rollout of Hunyuan 3D Smart Topology should begin with source-readiness checks, ownership of the submitted material, an agreed budget, and a written definition of the final smart topology deliverable. Before automation is enabled, the acceptance pass should verify that the returned asset opens correctly, fits the intended downstream toolchain, satisfies the project’s review criteria, and can be reproduced from the stored request and route identity tencent/hunyuan-3d/3.1/smart-topology.
