17 game shaders for Godot 4, each rendered before release
Shadewren is a set of short, commented shaders for 2D and 3D games in Godot 4.3+: outline, hit flash, dissolve, palette swap, glow pulse, drop shadow, hologram, wind sway, 2D water, pixelate, CRT, shockwave, colour grade, heat haze, toon, 3D outline and stylized 3D water. Each one was rendered in Godot 4.4 before release and has inspector sliders. The 14 2D and screen shaders also come as GLSL ES 1.00 ports for WebGL, Three.js, PixiJS or Phaser.

FAQ
Why not GameIdea's Stylized Water Shader?
If water is all you need, its $9.00 pack adds an underwater shader and a buoyancy script. Shadewren includes 2D and 3D stylized water among 17 shaders for $8.
Why not a PS1 kit like PSX Look?
PSX Look ($5.99 or more) is a focused PS1 rendering kit with vertex snapping and affine mapping. Shadewren is a general toolbox: outlines, hit flash, dissolve, CRT, shockwave, toon and more.
Aren't there free Godot shaders online?
Yes, and many are good. Shadewren gives you a tested, consistent set with sliders and WebGL ports in one place.
What does the Shadewren licence allow?
From the pack's LICENSE.txt (CyberMax Game Asset Licence 1.0): you may "use, modify, recolour, cut up and combine the assets in any number of games, apps, prototypes, game-jam entries, videos, streams, trailers, store pages and marketing for those projects, commercial or not" and "ship the assets inside compiled or packaged projects ... including projects that make money". You may not "resell, sublicense, give away or share the asset files themselves" or "use the assets to train or fine-tune an AI/ML model". "ATTRIBUTION is not required."
What are the limits?
Godot 4.3+ only for the .gdshader files (no Unity or Unreal versions); WebGL ports cover the 14 2D and screen shaders, not the 3 3D ones.
