Blender Python Scripting & Debugging Assistant
Debug and optimize Blender Python scripts and add-ons
What You Can Do
Debug, optimize, and troubleshoot Blender Python scripts, add-ons, and automation workflows with precision. This skill analyzes error messages, suggests performance improvements, and provides API best practices to help you build robust Blender tools and custom workflows.
Features
analyze stack traces and pinpoint root causes in scripts and add-ons
profile code bottlenecks and recommend efficiency improvements
resolve common Blender Python API problems and usage errors
create and refine efficient scripts for repetitive 3D tasks
measure execution time and memory usage patterns
follow Blender conventions for properties, operators, and UI
validate inputs and implement defensive coding patterns
Example Output
Debug Session: You provide a Blender script that crashes during batch rendering. Claude analyzes the traceback, identifies a missing context override in the operator call, and provides the corrected code with explanation.
Performance Analysis: You share a slow script that processes 10,000 mesh objects. Claude identifies unnecessary mesh re-evaluations in the loop, suggests using batch operations, and shows memory usage improvements of 60%.
Add-on Refactoring: You paste a custom panel that conflicts with Blender's UI. Claude refactors the code to follow Blender conventions, adds proper error handling, and explains registration best practices.
