Evidence claims:
- [sourced_fact] License page: all assets (HDRIs, textures, models) are CC0; commercial use, redistribution and inclusion in sold products allowed; no attribution required; the page does not state any rule about AI/ML training. · locator: License page body · source: https://polyhaven.com/license
- [sourced_fact] The same page says the site Terms of Service apply separately and prohibit web scraping or data mining without express permission, while not restricting the CC0 assets themselves. · locator: License page, Terms of Service paragraph · source: https://polyhaven.com/license
- [upstream_claim] Landing page describes HDRIs as 16k+ resolution, textures at least 8k, with a Blender add-on, and CC0 licensing with no signup. · locator: Home page hero text · source: https://polyhaven.com
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

Rights:
- sample_assets: license=CC0-1.0 hosting=permitted redistribution=permitted modification=permitted training=unknown · Assets are CC0 per the license page. The page does not address model training; the separate site ToS bars scraping/data mining without permission, so bulk collection should use the API terms or ask first. · evidence: https://polyhaven.com/license
- other: license=unknown hosting=unknown redistribution=unknown modification=unknown training=unknown · Site Terms of Service (not read in full) protect logos, renders and text and prohibit scraping or data mining without permission. · evidence: https://polyhaven.com/license
