Dataset Card for PBRPX Asset Library

Dataset Summary

This dataset contains metadata for 710 physically-based rendering (PBR) assets from pbrpx.com, a CC0 asset library. The dataset includes comprehensive information about 3D models, textures, and materials with detailed file listings, download URLs, texture resolutions, and categorization data. Assets include nature elements (trees, rocks), architectural materials (brick, concrete), and various other 3D models with complete PBR texture sets including albedo, normal, roughness, displacement, and other material maps.

Languages

The dataset is monolingual:

• English (en): Asset names, tags, and categories are in English.

Dataset Structure

Data Fields

Each asset in the dataset contains the following metadata fields:

• latinName: Scientific or Latin name for biological assets (e.g., "Abies" for fir trees)
• productName: Unique identifier name for the asset (e.g., "PX_Abies_Trunk_15")
• tagsEN: Array of English descriptive tags for the asset (e.g., ["tree", "trunk", "bark", "conifer"])
• productCategories: Nested object structure representing the hierarchical category organization
• physicalSize: Physical dimensions of the asset in centimeters (e.g., "174175190cm")
• file_list: Array of file objects, each containing:
  • downloadUrl: Direct download URL for the file
  • name: Filename
  • size: File size in bytes
• path_key: Unique path identifier for the asset
• thumbnail: URL to the thumbnail image
• preview: Array of preview image URLs
• resolutions: Array of available texture resolutions (e.g., ["1K", "2K", "4K", "8K"])
• categoryPaths: Array of category path strings for organization

Data Processing

The dataset was processed by adding a _dummy field with null value. This ensures compatibility with dataset libraries that may have issues with completely empty objects in nested structures. The _dummy field appears in empty category objects within the productCategories hierarchy and should be ignored during data processing.

Data Splits

The dataset contains a single split:
