+\* GDQuest: shader/code MIT; demo **art** is CC-BY-NC-SA — don’t ship the art.  
+\* Godot Shaders site: commercial code OK per policy, but GPL posts exist — check each shader.
 
 Default Shadertoy ports are often **CC BY-NC-SA** — [`docs/high-risk.md`](../../docs/high-risk.md).

+# GDQuest Godot Shaders
+
+Large MIT library of 2D/3D Godot shaders with demos (from GDQuest Shader Secrets / demos repo). **Shader/code = MIT (commercial OK).** Bundled **art textures/models = CC-BY-NC-SA 4.0** — do not ship those art files in commercial builds; swap in your own or CC0 art.
+
+## Notes
+
+- Godot 4 port in progress; Godot 3 tagged release `1.0.0` if you need a known-good 3.x tree
+- Prefer copying individual `.gdshader` files; leave NC demo art behind
+- Attribution example (shaders): `GDQuest Godot Shaders © GDQuest — MIT`
+
+## Evidence
+
+- Live `LICENSE` (2026-07-19): “demo's source code (script files, scene files, shaders…) … MIT”; “Art assets (image textures and 3D models) are CC-BY-NC-SA 4.0.”

+Godot 4 atmospheric day/night cycle (sun/moon/stars, fog, clouds, exposure). MIT addon — keep notice with redistributed copies. Third-party assets under `assets/thirdparty` have separate licenses — check before shipping those files.
