PBRify_Remix — ONNX export
ONNX re-exports of the CC0 SPAN models from Kim2091/PBRify_Remix: predict a tangent-space normal map, roughness map, and height map from a single albedo/diffuse texture. All credit for the weights goes to Kim2091.
Exported for QtMeshEditor
(issue #404), powering qtmesh material --generate-pbr, the Material Editor's
"Generate PBR maps from diffuse" button, the generate_pbr_maps MCP tool, and
the PBR stage of the image-to-3D pipeline.
The files QtMeshEditor downloads at runtime live in the shared
fernandotonon/QtMeshEditor-modelsrepo (top level). This repo is the standalone model card + mirror.

License & provenance
The upstream repo's LICENSE is CC0-1.0 and its README states the models were trained "exclusively on high quality CC0 content from ambientCG". (OpenModelDB's NormalV3 page lists "ambientCG + UltraSharpV2" as the training set — UltraSharpV2 is cc-by-nc-sa-4.0 — which contradicts the author's own statement; we treat the author's explicit repo LICENSE + "exclusively CC0" statement as authoritative. Documented for transparency.)
Reproducing

spandrel load → torch.onnx.export, opset 18, dynamic H/W).
