Delighting Benchmark v1 — Canonical Outputs

Canonical Paint3D and Hunyuan3D-2.0 texture-generation outputs for 30 test cases containing visible illumination and specular effects:

10 ABO matte cases
10 ABO glossy cases
10 Poly Haven PBR cases

Layout

Results are grouped by method:

paint3d/<case_id>/
hunyuan3d/<case_id>/

Every case contains exactly seven files:

input_image.png
input_mesh.obj
textured.glb
albedo_render.mp4
albedo_texture.png
gt_lit_render.mp4
gt_unlit_render.mp4

albedo_render.mp4 is a 3072x1024 H.264 three-panel turntable at 25 FPS, 4 seconds, and 100 frames. The two GT videos use the original source PBR asset and the exact Paint3D dr_eval normalization/camera contract shared by the Paint3D and Hunyuan3D-2.0 result videos. gt_lit_render.mp4 preserves strong directional/point lighting and shadows, while gt_unlit_render.mp4 is the flat reference-albedo pass. Both GT videos are H.264/yuv420p, 768x768, 25 FPS, 100 frames, and 4 seconds.

Validation

All 60 method/case packages passed the exact seven-file contract. All 60 unique GT videos were completely decoded, and all 120 method placements were validated for byte identity. Camera elevation, target, FOV, orbit phase, and rotation direction were audited at frames 0/25/50/75 against both methods. See: Cross-method textured-geometry/framing differences are retained separately as diagnostic warnings and are not conflated with camera/viewpoint failures.

ABO source assets retain their applicable Amazon Berkeley Objects terms. Poly Haven source assets are CC0. Paint3D and Hunyuan3D-2.0 retain their respective project/model terms.
