AI-powered 3D design in Blender. Works with Claude Code, Codex CLI, ChatGPT, Cursor, and more.

The first agent skill and plugin for Blender 3D — teaches AI how to create professional parametric designs, apply realistic materials, set up lighting, and render scenes through Blender's MCP (Model Context Protocol).

What This Skill Does

• Guides AI through a proven design workflow: analyze reference -> build simple -> verify from multiple angles -> iterate
• Includes reusable code patterns for parametric mesh generation (slats, planks, organic forms)
• Material library with wood, metal, concrete presets
• Scene setup with Cycles rendering, lighting, and camera helpers
• Troubleshooting guide for common Blender MCP errors
• Milestone management to save/restore design states

Prerequisites

1. Blender installed and open
2. Blender MCP addon running
3. MCP server configured in your AI tool:

   claude mcp add blender uvx blender-mcp
   

Install

Claude Code (Plugin)

claude plugin marketplace add jithinolickal/blender
claude plugin install blender@blender

Any AI Agent (Skill)

npx skills add jithinolickal/blender

Or install globally:

npx skills add -g jithinolickal/blender

The AI will automatically use this skill when working with Blender.

Design Workflow

This skill teaches AI a battle-tested workflow learned from real design sessions:

1. Understand before building — Analyze the reference, ask clarifying questions, identify simple geometric primitives
2. Start simple — Break design into parts, build one at a time
3. Verify from every angle — Take screenshots from 4+ angles (front, side, top, back)
4. Save milestones — Always save before making changes so you can revert
5. One change at a time — Iterate on single parameters, not everything at once

Examples

Parametric Slatted Planter

Starting from a reference image, the AI creates a circular disc made of 50 parallel wooden slats with a raised center bowl — all through natural language instructions.

Key Techniques Used

• bmesh for custom slat geometry
• Surface functions with smoothstep transitions
• Multiplicative bowl depressions (no holes)
• Procedural oak wood material (Noise + Color Ramp)
• Cycles GPU rendering with area lights

Built From Real Experience

This skill was created from extensive real-world design sessions — not theoretical documentation. Every instruction, every error fix, every design principle comes from actual iteration. The workflow prevents common mistakes that waste hours:

• Don't overthink the math — start with the user's simple description
• Never purge orphans (deletes materials)
• Use multiplicative depressions (subtractive creates holes)
• Always verify from the side view (catches dome vs flat issues)
• Save milestones before every change
