3D modeling, materials, lighting, rendering and animation with Blender 5 — headless renders (EEVEE and Cycles), product/packaging/poster mockups of 2D designs, turntables, glTF/GLB for the web (three.js / React Three Fiber, Draco), format conversion and STL for 3D printing — in a reproducible container. Use when the user wants to model something in 3D, make mockups of their designs, render stills or turntables, create 3D assets for the web, convert between 3D formats, prepare STL for printing, or script Blender with Python.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
2 rules. 0 are common, 2 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 3 edited versions we read keep these.
2
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 41
Keep modifiers live (Subdivision, Bevel, Mirror, Solidify) until export — non-destructive.
- Distinctive: line 45
Always look at a rendered still before committing to a long animation render.
“Common” is measured: kept by at least 6 in 10 of the 3 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
3D modeling (Blender 5)
Everything here needs the full image and runs in it automatically (bash <skill-dir>/scripts/<name>.sh …,
see design-sandbox). For hands-on modeling, use Blender on the desktop — the scripts work on the same .blend files.
Toolkit
| Tool | Use it for | CLI (in the container) |
| Blender 5 | Modeling, materials, lighting, rendering, animation, Python scripting | scripts/blender.sh -b … |
| EEVEE | Fast renders — mockups, previews, stylized work (software GL in the container) | engine BLENDER_EEVEE |
| Cycles | Photoreal renders on CPU in the container — use denoising + low samples | engine CYCLES |
| Bundled add-ons | glTF 2.0 (with Draco), FBX, OBJ/STL/PLY, Node Wrangler, Rigify | check.sh lists them |
| ffmpeg | Frames → MP4 | used by render.sh --anim |
Scripts
| Script | What it does |
check.sh | Blender version, Cycles devices, engines, add-ons (glTF!) |
blender.sh [args] | Blender in the design environment — use instead of blender |
render.sh scene.blend [--engine eevee|cycles] [--samples N] [--res WxH] [--frame N | --anim] [--out dir] | Headless still or animation; animations are encoded to MP4 automatically |
mockup.py | A 2D design (poster, cover, card, screenshot) as a lit 3D studio mockup: blender.sh -b --factory-startup -P <skill-dir>/scripts/mockup.py -- --image design.png --out mockup.png [--style tilt|flat|lean] [--bg '#f4f4f5'] [--res 1920x1080] [--save mockup.blend] |
turntable.py | 360° turntable of any model (glb/gltf/obj/fbx/stl/ply/blend): blender.sh -b --factory-startup -P <skill-dir>/scripts/turntable.py -- --model chair.glb --save chair-tt.blend, then render.sh chair-tt.blend --anim |
convert-model.sh in.X out.Y [--draco] | Converts between blend/glb/gltf/obj/fbx/stl/ply; --draco shrinks GLB for the web |

Rules of thumb
- Real-world scale (1 unit = 1 m); apply scale (Ctrl+A → Scale) before modifiers/export.
- Keep modifiers live (Subdivision, Bevel, Mirror, Solidify) until export — non-destructive.
- Preview small (
--res 640x360 --samples 8), final big. Use Cycles only for true glass/caustics/GI; 64–256 samples + denoising. - Animations render as PNG frames (crash-safe), then MP4 (
render.sh --animdoes both). - Web: GLB + Draco, textures ≤ 2K, < 50k triangles per hero model.
- Always look at a rendered still before committing to a long animation render.
Does it work?

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
