What problem does it solve?

This Skill addresses common pitfalls and complexities in Blender's Python API, ensuring your scripts run reliably, avoid crashes, and handle threading, undo/redo, and event handling correctly.

Core Features & Use Cases

• Thread Safety: Learn how to safely execute bpy calls from background threads.
• Undo/Redo Management: Understand how to prevent crashes and data corruption when users undo or redo actions.
• Event Handling: Master bpy.app.timers and bpy.msgbus for responsive and efficient script execution.
• Spatial Queries: Efficiently use KDTree and BVHTree for point and ray intersection tests.
• Use Case: Prevent your Blender add-on from crashing when a user performs an undo operation by correctly managing bpy references, or ensure your background rendering script doesn't freeze the UI by properly scheduling tasks.

Quick Start
