Auto UV Unwrap & Pack: Seamless UV Mapping

This powerful Blender add-on automates UV unwrapping and packing with customizable seam marking for faster and more efficient UV layout creation. Perfect for both simple and complex models, Auto UV Unwrap & Pack helps you achieve clean, optimized UV maps with minimal effort. Key features include dynamic control over seam angles, the ability to mark seams based on angle continuity, and real-time visualization of seams as you adjust the settings.

Features:

• Angle-based seam marking: Automatically marks seams based on face angle differences for improved UV layout.
• Dynamic angle threshold: Adjust the angle threshold live with an intuitive slider for real-time results.
• Clear seam option: Toggle visibility of seams for easy debugging and testing.
• Central seam marking: Automatically marks a central seam based on object symmetry (useful for cylindrical shapes).
• Smart packing: Automatically unwrap and pack UVs for selected objects with efficient space usage.
• Compatible with complex models: Works with both low-poly and high-poly models for seamless integration into your workflow

Instructions:
