Evaluation Data: IM-MA mesh geometry defect breakdown across 101 exports

Author: topohealCreated Aug 4, 2026Updated Aug 4, 2026

Hi IM-3D / Meta GenAI team,

I ran an open, reproducible geometry QA census (3dqa-benchmark) across 2,307 generative exports from 23 models.

IM-MA Metrics (n=101):

  • Non-watertight: 84.2%
  • Non-manifold edges: 53.5%
  • Missing UVs: 100%
  • Vertex-colour-only exports: 100%
  • Exceeding 30k budget: 0.0%

Full reproducible CLI runner (pip install 3dqa) and aggregate reports are available at: https://github.com/alza123123/3dqa-benchmark
