28, 2025 improvements rigging mode when using rigging tools without a properly configured avatar, a warning log will now be displayed instead of an error popup the log will indicate which bones require setup uv editor scale gizmo adjusted the scaling ratio of the gizmo and prevented the minimum value from going below 0 bug fixes general fixed a data loss issue when overwriting a prefab instance with a non prefab object if multiple prefab instances already existed in the scene fixed errors that occurred when loading models from older umodelerx versions fixed a race condition issue related to edgeseam during mesh building fixed a conflict issue with the unity polybrush package fixed an issue where the selection color would sometimes turn white when installing a new package fixed an error related to avatar settings when umodelerizing a skinnedmesh rigging mode fixed a bug where some bone data was incorrectly copied when modifying the bone hierarchy curvemesh fixed an issue where alt+ctrl+left click would not navigate to the manual page 1 1 2 | april 18, 2025 bug fixes general fixed an issue where the prefab was deleted after copying and saving a child object of a prefab instance modeling mode inset tool fixed an issue in the command system when performing undo/redo while modifying property values bevel tool fixed a bug that occurred when running the tool repeatedly multi mirror tool fixed an issue when selecting with non umodelerx objects repeat tool fixed a bug where the overlay would disappear when reapplying the bevel tool to vertices material tool fixed an issue where the material was not refreshed when reapplying after undoing a material change uv editor fixed a jittering issue when rotating uvs of faces with inconsistent shapes curvemesh fixed an issue where deleting a curve point with the delete key would also delete the object 1 1 1 | april 9, 2025 improvements modeling mode parallel tool after making an adjustment, modifying the distance value will now allow re editing of the previously created parallel curvemesh improved the connection at the end of closed curvemesh shapes to appear smoother bug fixes general fixed an error related to snapenabled when importing in unity 2023 1 fixed a prefab related error when converting an editable mesh with a sticker layer into a prefab modeling mode erase tool fixed an error that occurred when deleting edges or vertices based on surrounding uv conditions pushpull tool fixed an issue where holes would disappear unexpectedly uv param tool now retains values as much as possible when used within drawing group operations face color tool now retains values as much as possible when used within drawing group operations painting 3d rect fill fixed an issue where the brush shape would appear
