Hunyuan3D output is a starting point, not proof that an asset is production-ready. A topology diagnosis pass should distinguish generation artifacts from deliberate form before anyone spends time polishing the result.
For Hunyuan3D output, keep the topology diagnosis pass focused on non-manifold geometry, density distribution, and deformation flow. Make one controlled change at a time and retain enough evidence for another person to repeat the decision.
Identify non-manifold edges, self-intersections, thin surfaces, poles, and density spikes before deciding whether retopology is necessary. Apply this topology diagnosis guidance to the actual Hunyuan3D output delivery path.
