blender-errors-data

What problem does it solve?

This Skill helps developers diagnose and fix common ReferenceError and other data access issues in Blender Python scripting, ensuring scripts remain stable across undo/redo, file operations, and version updates.

Core Features & Use Cases

• Error Diagnosis: Identifies root causes for ReferenceError, KeyError, and crashes related to stale data pointers.
• Safe Data Patterns: Provides clear rules and decision trees for robust bpy.data access.
• Version Compatibility: Addresses specific pitfalls in Blender 5.0+ IDProperty changes.
• Use Case: A script crashes after a user performs an undo operation. This Skill helps identify that direct bpy.data references were stored and guides the developer to use name-based lookups instead.

Quick Start

Use the blender-errors-data skill to understand why accessing bpy.data after an undo operation causes a ReferenceError.
