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:
