atlas-uv-fitting SKILL.md skillA
atlas-uv-fitting from max-786/claude-3d-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add max-786/claude-3d-harness/atlas-uv-fitting@git:20260921.d4bf893Pins git:20260921.d4bf893 in mdr.lock. Pin the fingerprint instead.

Detect texture-atlas regions and map each source part to its own UV rectangle or projected UV surface. Use when a texture pack must fit a Blender model 1:1, when textures look off/stretched, when alpha decals or lightmaps are provided, or before exporting a textured GLB for a brand mascot/logo.
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
# Atlas UV Fitting This skill exists because assigning a texture material is not the same as fitting a texture. ## Supplemental map sanity rule Do not blindly wire emissive/roughness/bump/lightmap images into every atlas-mapped part. First verify the supplemental map has the same UV layout and semantic region as the basecolor. If it contains aura dots, guide marks, lightmap blobs, or decorations outside the part, leave it disconnected for that mesh and use constant roughness/bump plus explicit edge/glow geometry instead. ## Hard rules - Atlas textures must be mapped by region; never apply the full atlas to every structural mesh. - Front-facing hero surfaces use front-projected UVs or a source-region rectangle. - Side/back surfaces use their own UV islands or procedural/baked fills. - Roughness, bump, normal, AO, and lightmap images are `Non-Color`. - Alpha decals must use alpha-connected materials and no black backing planes. - Base GLB should not include reference planes or optional aura unless explicitly requested. ## Workflow 1. Run `scripts/atlas_region_detector.py` on basecolor/decal/aura atlases. 2. Name regions semantically in `atlas_regions.json`. …

How to install
mdr add max-786/claude-3d-harness/atlas-uv-fitting@sha256:79072a7965bd535eThe line at the top of this page pins the label git:20260921.d4bf893, 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.
