What it does
Render Glb is an agent skill from rawwerks/VibeCAD. Render GLB 3D models to PNG images for visual verification. Use when you need to SEE your generated 3D model, verify geometry, check visual correctness, or show results to users. Triggers on: render GLB, preview model, visualize 3D, see my model, check geometry, visual verification, screenshot model, model preview.
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering 3D graphics and WebGL. The repository describes itself as: A library of Claude Code skills for teaching coding agents how to use various CAD tools. The licence is MIT.
When your agent uses it
- You need to SEE your generated 3D model
- Verify geometry
- Check visual correctness
- Show results to users
Example prompts
- “/render-glb”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Generate model → export GLB
- Render GLB → PNG
- Read PNG → see what you built
- Iterate if needed
What it can do on your machine
Read from SKILL.md and the folder at commit 609e888. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
bunx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
npmjs.comgithub.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Render Glb loads about 527 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 132 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Render GLB 3D models to PNG images for visual verification. Use when you need to SEE your generated 3D model, verify geometry, check visual correctness, or show results to users. Triggers on: render GLB, preview model, visualize 3D, see my model, check geometry, visual verification, screenshot model, model preview.
Render GLB to Image
Render 3D GLB files to PNG images so agents can visually verify their work.
Zero-Setup with bunx
bunx render-glb model.glb output.pngNo installation required. First run downloads the tool, subsequent runs are instant.
Why This Matters
Agents can generate 3D models but typically can't see them. This creates a visual verification loop:
- Generate model → export GLB
- Render GLB → PNG
- Read PNG → see what you built
- Iterate if needed
Basic Usage
# Render with defaults (good for most cases)
bunx render-glb model.glb preview.png
# Then read the image to see your work
# (use Read tool on preview.png)Options
bunx render-glb <input.glb> <output.png> [options]
Options:
--width <n> Image width in pixels (default: 800)
--height <n> Image height in pixels (default: 600)
--background <hex> Background color (default: #808080)Visual Verification Workflow
When building 3D models, use this pattern:
# 1. Build your model
from build123d import Box, Sphere, export_gltf
model = Box(20, 20, 20) + Sphere(radius=15)
export_gltf(model, "./model.glb", binary=True)# 2. Render to image
bunx render-glb model.glb preview.png# 3. Read the image (using Read tool)
# Now you can SEE what you built and verify it's correctIntegration with CAD Skills
This skill complements:
- build123d - Python CAD modeling
- Any tool that exports GLB format
Typical workflow:
- Use CAD skill to generate geometry
- Export to GLB
- Use render-glb to verify visually
- Iterate if model isn't correct
