 # Charge materials (Blender Studio)
 
-Procedural materials from Blender Studio’s *Charge*. **CC-BY** — bake to PBR maps for other engines. Confirm asset page license.
+Procedural materials freebie from Blender Studio’s *Charge* gallery. Historically treated as **CC-BY** (bake to PBR for other engines), but this run the gallery page shows the freebie card **without an on-page license badge/quote** — keep `needs-review` until the freebie’s own license statement is readable.
+
+## Notes
+
+- Prefer [ambientcg](ambientcg.md) / [poly-haven](../environment/poly-haven.md) for clear CC0 PBR
+- Blender.org website CC-BY does **not** substitute for this asset’s grant
+- If you obtain the `.blend`, read any LICENSE/README inside before shipping
+
+## Evidence
+
+- Live gallery (2026-07-19): “Charge Material Asset Library - Freebie” listed; no CC-BY/CC0 text extracted from the asset surface → cannot promote to `active`

 # Fab / Quixel Megascans (Standard License)
 
-Photogrammetry rocks, foliage, ground materials, decals, etc. **Only** assets under **Fab Standard License** are treated as multi-engine in Round 3 research — **Epic Content License** stays Unreal-locked. No standalone redistribution. Verify the license badge per download; do not catalog as CC0.

+## Notes

+- Prefer [poly-haven](../environment/poly-haven.md) / [ambientcg](ambientcg.md) / Kenney nature kits when you need clear CC0

 # Poly Pizza
 
-Aggregator of low-poly models from multiple creators. License is **per-model** — verify before shipping. Useful discovery surface; not a single license umbrella.
+Low-poly model aggregator (10k+). **Per-model `Licence` field** — live samples include **CC0 1.0** (many Quaternius) and **CC-BY 3.0**. Prefer catalogued primaries ([quaternius](quaternius.md), [kenney](kenney.md)) over re-downloading mirrored packs here.
+
+## Notes
+
+- No site-wide license page (`/license` 404 this run)
+- Open each model’s badge before shipping; filter creator when you already have the primary source
+- Attribution required when the model is CC-BY (not when CC0)
+
+## Evidence
+
+- Live model [Adventurer / Quaternius](https://poly.pizza/m/5EGWBMpuXq) (2026-07-19): JSON `Licence: "CC0 1.0"`
+- Live model [Character Base / madtrollstudio](https://poly.pizza/m/qbDLeTtb8K) (2026-07-19): “Creative Commons Attribution” → CC-BY 3.0 → keep catalog-level `needs-review`
