While running Zen Unwrap in Blender 5.0.0, the operator fails with an UnboundLocalError referencing the variable p_init_positions inside zen_unwraputils.py during the ci_sel_sel_only_face stage. The unwrap process stops immediately and throws a full traceback. It appears the variable is only conditionally created and is not initialized in certain mesh/selection states, causing the unwrap operator to crash. What I was doing: Blender 5.0.0 ZenUV latest version Multiple objects selected in Edit Mode Faces selected UV Sync Selection may have been on Triggered Zen Unwrap from the ZenUV panel UVPackmaster 3 installed and visible but not directly involved Immediately received the traceback and the unwrap did not execute Observed Behavior: Zen Unwrap crashes with the following ending line: UnboundLocalError: cannot access local variable 'p_init_positions' where it is not associated with a value Expected Behavior: Zen Unwrap should initialize all required variables and continue the unwrap process without throwing an exception. Additional Notes: The crash seems related to a code path where p_init_positions is not instantiated before being used, likely when certain face selections or island conditions are met. https://cdn.discordapp.com/attachments/1440448584154611893/1440448584486228009/image.png?ex=6949b348&is=694861c8&hm=d8ce87a62c88345dc48c6431a5285b6f43a91cfb46f86e86fb996715449f9b8c&

Thank you for the very detailed report. We will fix it in the nearest release

Could you please provide me with the scene in the same state as it was at the moment the error occurred, so I can reproduce the issue on my side? Also, please specify how the operator properties were configured and what exactly was selected before running Zen Unwrap.

Not a problem, one second
