scenario-unreal-materials SKILL.md skillA
scenario-unreal-materials from scenario-labs/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add scenario-labs/skills/scenario-unreal-materials@git:20260926.9ac7861Pins git:20260926.9ac7861 in mdr.lock. Pin the fingerprint instead.

Use when a UE5 task involves materials or textures: a master material and instances for a kit, Substrate or legacy, Blendable vs Adaptive GBuffer, glass, emissive screens, decals, edge wear and dirt, landscape layers and RVT, toon or cel shading, "too many shaders" or shader permutations, static switches, usage flags, texture compression (BC7, normal maps, ORM packing, sRGB), texture memory, or "is this material expensive".
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
# Unreal materials (master materials, Substrate, textures, shader cost) Expert level means a few master materials whose instances cover the kit, a known and budgeted permutation count, cost proven in milliseconds on a fixed camera, and physically plausible values before any artistic push. The graph is authored once (scripted build or template); everything else is instances, Custom Primitive Data and textures that follow a role policy. Never trust the instruction count or a pretty preview. If a sibling skill named here is missing from your available skills, ask the user to install it (`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and flag the gap. **REQUIRED BACKGROUND:** scenario-unreal-expert (channels, review loop, 5.8 traps). **Status (2026-09-24):** Unreal is not installed; offline tests pass (`tests/code/unreal-materials/run_all.sh`, editor layer on a fake `unreal`). Every snippet is **not yet run in Unreal**: run P0 first. ## Stance (the expert delta) …

How to install
mdr add scenario-labs/skills/scenario-unreal-materials@sha256:42bd8d485c9be993The line at the top of this page pins the label git:20260926.9ac7861, 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.
