Preferences : The minimum value for wireframe-related settings has been adjusted to 1.
UModelerize : When UModelerizing a prefab or model such as OBJ/FBX, a dialog now allows unpacking and UModelerizing in one step. This behavior can be configured via Preferences.
Tool Input Hint : A shortcut to open the manual has been added and is now displayed in tooltips.
Modeling Mode
Elements Group Tools: Added a Preserve UVs option, which moves UVs proportionally when elements are moved.
Drawing Group Tools: Now better preserves UVs when editing planar surfaces with UVs.
Isolate Tool: Improved performance by reducing excessive holding during range selection.
Quadify Tool: Added an option to preserve UVs during quadification.
Painting & Rigging Mode
Object Tool: A reworked version of Object Mode, allowing users to exit edit states across both modes. Accessible from the top toolbar.
Painting 2D Editor
While holding Shift, canvas rotation now snaps in 15-degree increments.
Bug Fixes
General
Preferences: Corrected the position of the Reset to Default button.
Modeling Mode
Align Tool: Fixed an issue where the tool did not operate continuously.
Slice Cut Tool: Fixed an issue where the axis rotated incorrectly when rotating the cutting plane.
Painting 3D
Fill Layer:
Fixed thumbnail and preview rendering when using Rotate and Tile values.
Fixed alpha rendering issues under certain conditions.
Tool Input Hint: A new Tool Input Hint button has been added below the EdMesh Info in the top-left corner of the Scene view. Clicking this displays available actions and shortcuts for the active tool. This button can be toggled in Preferences.
Modeling Mode
Edge Flip Tool: A new tool that lets you flip the triangulation direction of selected faces. (Pro only)
Improvements
Added import option settings for .obj files.
Improved performance when working with high-polygon meshes, including selection, picking, using the Decimate Modifier, and mesh building.
UModelerize
UModelerize no longer creates a duplicate object; it now directly converts the original object into a UModelerX object. An exception applies to FBX/OBJ prefab instances, which must be unpacked before UModelerizing.
You can now UModelerize FBX assets directly from the Project view via the UModelerX > UModelerize FBX menu. This creates a new prefab with UModelerX data.
Scene Toolbar
The “Enable Scene Toolbar” setting now ensures all toolbar buttons are fully hidden when disabled.
Rigging Mode
Added tooltip explanations for the Disable GPU Option.
Favorite Tool
Pivot and Reset X Form tools have been added to the default Favorite Tool list.
Bug Fixes
Modeling Mode
Fixed issues where manual links were not properly created in certain tools.
Fixed abnormal UV generation when using the Stair Tool.
Body Bone Auto Setup: Automatically configures Human Body Bones based on bone names. This uses Unity’s required bone set as a reference.
Clear Body Bone Data: Clears all assigned Human Body Bones.
Improvements
Modeling Mode
Delete GameObject: Pressing the Delete key now removes the GameObject. The only exception is when using Erase in the Element Tool after selecting an element.
Escape Tool: Right-click now exits to the Object Tool. This action does not trigger if dragging occurs. For tools like PolyLine and Knife, it exits their active state.
Painting Mode
Color Picker: Improved color picker functionality in both 2D and 3D Painting. Pressing the ‘I’ key while using the Brush or Fill Tool now brings up the picker, which captures the exact on-screen color.
Rigging Mode
Build Bone Tool: The Turn 90 button has been removed to clarify bind pose setup. Going forward, humanoid rigging should start from the front-facing direction.
Renamed bones in the Human rig structure to match Unity’s avatar naming convention.
Rigging Tool: Clicking on an empty area now deselects the currently selected bone.
Bug Fixes
Modeling Mode
Rectangle Tool: Fixed an issue where adjusting values while working over existing faces caused errors.
Disk Tool: Fixed an issue where adjusting values while working over existing faces caused errors.
SideStair Tool: Fixed an issue where adjusting values while working over existing faces caused errors.
Bridge Tool: Fixed a bug where the tool wouldn’t activate when two connected edges were selected.
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.
Added an option to move vertices and edges along existing edges.
Quadify Tool
A tool for converting part or all of a mesh into quads.
Isolate Tool
Allows selection based on independent mesh islands.
Multiple Objects
Multi Align Tool
Aligns multiple objects according to a chosen reference.
Curve Mesh Component
A new component for creating mesh in the shape of a curve. You can add, remove, or move points that make up the curve, then control its type and volume to generate mesh in the desired form.
