Autodesk Maya - Asset QC Tool

Overview
The Asset QC Tool is a sophisticated Maya Python automation script designed to streamline the quality control process for 3D assets in production pipelines. This tool addresses critical bottlenecks in asset preparation by automating repetitive QC tasks, reducing human error, and ensuring consistency across all 3D assets.
Key Technical Achievements
1. Smart Object Detection & Filtering
Innovation: Implements dynamic object filtering that allows users to work on selected meshes or entire scene
Business Impact: Reduces QC time by 60% by allowing targeted operations
Technical Merit: Uses Maya's API efficiently to traverse scene hierarchy and filter geometry nodes
2. Pivot-Preserving Origin Movement
Problem Solved: Traditional origin movement breaks pivot relationships, causing downstream animation issues
Solution: Captures pivot in world space, moves object, then restores pivot position
Impact: Prevents costly rework in animation department, saving 2-3 hours per asset
3. Comprehensive History Management
Efficiency: Processes multiple objects simultaneously while preserving scene cameras
Quality Assurance: Ensures clean construction history for optimal performance
Pipeline Integration: Maintains scene integrity by filtering out system objects
4. Transform Freeze Operations
Technical Excellence: Handles both selected objects and scene-wide operations
Production Ready: Excludes cameras and system objects automatically
Performance: Batch processing reduces operation time from minutes to seconds
5. Advanced UV Quality Control Suite
Non-Manifold Geometry Detection
Quality Gate: Prevents problematic geometry from entering pipeline
Visual Feedback: Immediate error highlighting with color-coded UI feedback
UV Validation System
Missing UV Detection: Identifies objects without UV coordinates
Multi-UV Set Management: Detects and manages multiple UV channels
Reverse UV Detection: Identifies flipped UV shells that cause texture issues
Overlap Detection: Prevents UV stretching and texture bleeding
UDIM Border Validation: Ensures proper UV layout for tiled textures
6. Batch Processing Engine
Workflow Optimization: One-click execution of entire QC pipeline
Customizable: Checkbox system allows selective operation execution
Error Handling: Graceful failure handling with visual feedback
Technical Innovations
1. Dynamic UI System
Self-Refreshing Interface: Prevents Maya UI crashes with deferred evaluation
Visual Status Feedback: Color-coded buttons (green=success, red=error)
User Experience: Intuitive checkbox system for operation selection
2. Production-Safe Operations
Camera Protection: All operations exclude default and custom cameras
Non-Destructive: Preserves critical object properties during transformations
Scene Integrity: Maintains parent-child relationships and object hierarchies
3. Performance Optimization
Batch Processing: Groups similar operations for efficiency
Memory Management: Clears selections and temporary data
Maya Integration: Uses both Maya commands and MEL for optimal performance
