Broad reflections are learned. Fine blade grain and sharp highlights remain imperfect.

About this result

12 training passes; the coverage budget was reached before the convergence rule was met. Uses synthetic proxy geometry for shadows and normals. No ground-truth material textures.

Mobile uses a simplified 10 MB model and saves 960 × 640 RGB16 images. Full detail uses the original 288 MB model and enables native 4K export. Requires WebGPU. All rendering happens on your device; model files are delivered from R2.
