BUG FIXES

Changelog

I'm sorry because of my lack of testing, which caused a serious issue with the auto-generated stitching edges in version 1.05, which has now been fixed.

Changelog

• Removed bpy.ops.mesh.select_all, using bmesh to set face selection directly for better performance.
• Optimized context switching, reducing unnecessary operator use while retaining UV editor area for official seam generation.

Changelog

• Fixed Basis shape key check to use len(mesh.shape_keys.key_blocks) instead of name-based lookup, supporting renamed or reordered keys.
• Removed UI panel and moved operator to Object menu for simplicity.
• Fixed AttributeError when object has no shape keys by adding None check for mesh.shape_keys.
• Fixed excessive face splitting by refining UV island detection using vertex UV coordinate sets instead of per-face comparisons.
• Added a dialog with mutually exclusive options ("Use Existing Seams" and "Generate Seams") to skip seam generation in some cases for improved performance, with a warning for potential errors when generating seams.
• Improved error handling for context-related RuntimeErrors with user-friendly messages.
• Changed Object menu display name from "UV Flatten" to "Flatten UV to SK" to make the function easier for users to understand.
• Optimized bpy.ops.uv.seams_from_islands() by removing seam count validation, splitting the model directly based on generated seams.
• Added a dialog warning under "Generate Seams": "Some older files may error; copy object to a new scene to avoid issues," and updated error messages with the same advice.
