Physically based materials in Blender 5.2 - metal/roughness rules, Principled BSDF inputs, color spaces (sRGB vs Non-Color), measured albedo/F0 values, texture-set auto-wiring, ORM channel packing, DirectX vs OpenGL normals, alpha modes, displacement, view transforms (AgX, Khronos PBR Neutral), engine-ready material rules. Use when creating, fixing, or exporting materials and textures.
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
# PBR Materials The execution model is in `blender-core`. Measured values are in [references/pbr-values.md](references/pbr-values.md). ## Fast paths - Texture set → material: `scripts/build_pbr_material.py -- --name M_Crate --textures //tex/crate --objects SM_Crate`. It detects maps by filename (Poly Haven, ambientCG, Substance, UE suffixes), sets color spaces, splits ORM, flips DirectX normals, and routes AO to glTF. - Solid physically-plausible material: `--preset gold|iron|plastic|rubber|wood|glass|skin|...` with an optional `--color R G B` (sRGB). ## The rules (violations are what make renders look "CG") 1. **Metallic is binary**: 0 (dielectric) or 1 (raw metal). Use in-between values only on transition pixels (dust or rust edges on metal). Painted metal counts as dielectric. 2. **Base color = albedo with no lighting**: no baked shadows/AO/highlights. Dielectric range is sRGB ~30–240 (linear 0.012–0.87): charcoal ≈ 50, fresh snow ≈ 240. Metals: base color = F0 reflectance, sRGB 180–255, never dark. 3. **Roughness carries the realism**. Break it up with grunge, smudges and wear. A constant roughness value looks fake; vary it ±0.1–0.2 across a surface. …

How to install
mdr add el4cteo/blender-skills/blender-pbr-materials@sha256:a067d2268abd75e5The line at the top of this page pins the label v1.2.0, 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.
