Use when authoring or debugging a shader, material, VFX, or full-screen post-process in a game engine — Godot 4.x `.gdshader`, Unity 6 URP/HDRP, Unreal 5.x Materials, effect recipes, shader performance. NOT gameplay or engine-API code (that is `godot`/`unity`/`unreal`), NOT physics (`gamedev-physics`), NOT build variant stripping (`gamedev-shipping`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Shaders & VFX (game engines) Author shaders, materials, and full-screen effects across Godot, Unity, and Unreal. One mental model — the GPU pipeline — mapped onto each engine's authoring surface, plus recipes for the effects people actually ask for. ## Version contract — read first Target the current stable line of each engine and never emit its retired APIs. If unsure a symbol is current, say so rather than guess. | Engine | Target | Never emit → use instead | | --- | --- | --- | | **Godot** | 4.x (4.4/4.5 stable) | `SCREEN_TEXTURE`/`DEPTH_TEXTURE`/`NORMAL_TEXTURE` built-ins → declare a `uniform sampler2D … : hint_screen_texture` / `hint_depth_texture` / `hint_normal_roughness_texture`. `hint_color`/`hint_albedo` → `source_color`. `hint_white`/`hint_black` → `hint_default_white`/`hint_default_black`. GLES2-era guides. | …

How to install
mdr add ericrisco/rsc-harness/gamedev-shaders@sha256:9552bdd8a454565dThe line at the top of this page pins the label git:20260729.ad893da, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
