Polyhaven PBR Cycles 576 (Azim21, Dynorbit, Multi-Light)

Evaluation set of Poly Haven objects rendered with Blender Cycles for high-quality PBR material and shape generation evaluation.

This is the packaged copy of the evaluation dataset for SViM3D (https://huggingface.co/StabilityLabs/svim3d).

Summary

Field	Value
Assets	348 Poly Haven objects
Shards	`00/` `01/` `02/` `03/` (87 `.tar` files each)
Size	~77 GB
Resolution	576 × 576
Views per illumination	21 azimuth orbit frames
Orbit	dynamic ("drunk") azimuth orbit, elevation about −10° to 30°
Illuminations	4 HDRI lighting conditions per object (`illumination_00` … `03`)
Renderer	Blender Cycles, 256 samples
FOV	0.591627 rad
Meshes	GLB saved per illumination

Source models are CC0 Poly Haven assets. Packaged HDRIs include mixed sources (HDRI Haven and iHDRI).

Layout

config.yaml
00/*.tar
01/*.tar
02/*.tar
03/*.tar
mask/                 # small debug RGBA masks

Each archive is named {asset}_4k.tar and unpacks to:

{asset}_4k/
  illumination_00/
    {asset}_4k.glb
    rgba/rgba_XXXX.png
    diffuse/diffuse_XXXX.png
    metalrough/metalrough_XXXX.png
    normal/          # EXR normals
    depth/depth_XXXX.exr
    frame_XXXX.json  # camera + envmap metadata
    frame_XXXX.npy
  illumination_01/
  illumination_02/
  illumination_03/

frame_*.json includes camera radius/azimuth/polar, FOV, image size, and the HDRI name (sky_name, skymap_z_rotation).

Download

bash
