What This Skill Does

The Blender AI Skill is an essential assistant for 3D artists and technical developers working within the Blender ecosystem. It provides expert guidance on optimizing workflows, troubleshooting common modeling errors, and ensuring that assets are perfectly prepared for export to game engines like Unity, Unreal, and web-based platforms. The skill acts as a bridge between complex Blender operations and standard industry best practices, covering critical areas such as transform application, modifier stack management, normal orientation, and UV mapping logic. By automating the verification of model integrity, it helps users avoid common pitfalls like non-uniform scaling, flipped normals, and improper origin points that often cause rendering or gameplay bugs.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/ivangdavila/blender Ensure you have your OpenClaw CLI authenticated and configured to pull from the primary openclaw/skills repository.

Use Cases

• Automated Asset Cleanup: Use the skill to verify if a model is ready for export, checking for unapplied transforms and degenerate geometry.
• Technical Pipeline Debugging: Troubleshoot why exported meshes appear distorted, have broken materials, or possess incorrect pivot points in game engines.
• Workflow Optimization: Request procedural guidance for complex modifier stacks, such as setting up non-destructive modeling sequences for character or environment assets.
• Python Scripting Assistance: Generate bpy scripts to automate repetitive tasks like applying transforms to entire scenes or batch-exporting objects with specific settings.

Example Prompts

1. "Check my current selection for potential export issues. Are there any unapplied transforms, flipped normals, or overlapping UVs?"
2. "Explain the correct modifier order for a model using a Mirror, Bevel, and Subdivision Surface modifier, and write a Python snippet to apply them all."
3. "I'm exporting a rigged character to Unity. What are the recommended FBX export settings to ensure the rotation and scale are correctly interpreted?"

Tips & Limitations

• Proactive Checking: Always use Shift+N to recalculate normals before finalizing your mesh. Blue indicates outward-facing normals, while red suggests a potential rendering issue.
• Edit vs Object Mode: Remember that most bpy.ops require the agent to switch the context to OBJECT mode before executing, or the operation will fail silently.
• Non-Destructive Workflow: Avoid applying modifiers until you are absolutely certain of the geometry, but always apply scale (Ctrl+A) early to avoid deformation issues in game engines.
• Limitations: The agent cannot directly modify your open Blender file without an active connection via the Python API; ensure the Blender Remote Python server is accessible if live-editing is required.
