Beta Tools: Tools in the beta stage, marked with a green icon, are feature-complete but undergoing bug fixes and stability improvements.
Experimental Tools: Tools still under significant development, marked with a blue icon, may experience major changes or removal. Experimental tools can be enabled via the settings menu.
Bug Fixes
General
Fixed an issue where Undo/Redo operations would become misaligned after a script reload.
Modeling Mode
Create Shape As a New Object: Resolved an issue where the pivot position of a new shape would incorrectly match the previous object's pivot position when this option was enabled.
PushPull Tool:
Expanded collision detection from nearby edges to all faces for improved accuracy.
Fixed errors occurring when using PushPull on holes.
Export
Resolved an issue where vertex color values were not correctly exported during Ply Export.
Added functionality to split faces with line tool click points that intersect with faces. However, splitting a face into parts by passing through a hole is not allowed.
The PolyLine Tool now preserves UV unwraps as much as possible when splitting faces.
InsertVertex Tool
Maintains UV unwrap integrity as much as possible for faces around the newly added vertex.
Bridge Tool
No additional faces will be created if the faces already exist.
Bug Fixes
Modeling Mode
Shape Tools
Fixed an issue where mouse picking during shape creation was not working properly.
Element Tools
Resolved a rendering issue where backfaces were not displayed during Backface Select in URP.
UVEditor
Unwrap Tools
Fixed a bug where UVs of holes were incorrectly positioned during unwrapping.
UModelerize Prefab:This new feature allows you to convert prefabs into UModeler X objects seamlessly. You can choose to either modify the original prefab directly or create a separate copy, providing flexibility based on your workflow needs.
Bug Fixes
Modeling Mode
Vertex Tool:
Fixed an issue where path selection using double-click did not work.
Inset Tool:
Resolved a bug where property adjustments after face selection were not functional.
Fixed an issue where undoing actions caused the mesh structure to break.
PushPull Tool:
Adjusted to ensure debug messages are no longer displayed unnecessarily.
Height Snap now only activates when the Control key is pressed.
PolyLine Tool:
Fixed an issue where faces could invert at certain positions when concave shapes were present.
Resolved a problem where undoing line creation caused snapping errors, resulting in duplicate vertices at the same location.
PolyLine Tool: A tool for creating consecutive lines. If the lines form a face, the face is created based on the camera's view direction. Sketch-based operations (e.g., hole creation, face trimming) are supported when overlapping with a plane.
Custom Coordinate Tool: A user-defined coordinate system tool has been added to the Misc group, allowing users to configure and view custom coordinates in the Coordinate Toolbar.
Improvements
Modeling Mode
Element Tool: Snap Rotation is now available in the Element group's Translate section, allowing vertex alignment by click-dragging to face another vertex.
Connect Tool: Users can now set the option to select edges after using the tool via Preferences > Modeling > Selection After Connect.
Rigging Mode
Create Root Bone Structure: A button has been added to generate objects suitable for UModelerX rigging workflows.
Bug Fixes
General
UV and Hotspot Editor: Fixed color mismatches between the editor's textures and Unity's preview.
Export: Resolved issues when exporting .obj models with multiple materials.
Fixed issues when saving UModelerX objects with scene folder save options enabled in multi-scene setups.
Added support for multi-UV channels in UModelerize.
Modeling Mode
Weld Tool: Adjusted to preserve UVs.
UV Editor
UVSelect Tool: Modified to ensure that if the drag start point is a UVFace, holding Shift or Control will activate the Rect Select function instead of moving the face.
Bug Fixes
General
EdMesh Info: Fixed an issue related to memory garbage collection.
Modeling Mode
Eraser Tool: Resolved an issue where the tool caused models to disappear when used on unwrapped models.
Bridge Tool: Fixed a problem preventing the tool from functioning on unwrapped models.
UV Editor
Fixed issues related to saving multi-UV channels.
Resolved a bug where the Island Boundary update was delayed when switching UV channels.
Fixed a bug that occurred when updating UVIslands while changing UV channels.
UVFace Tool: Fixed an issue where leftover loops remained after canceling UV selection.
Unwrap Tool Group: Ensures the current UV channel's creation state is checked during unwrapping.
UVIsland Tool: Corrected a bug where all UVIslands were selected regardless of the current material.
Auto Layout Tool: Fixed issues occurring with multi-UV channels.
Sew Tool: Resolved problems related to multi-UV channels.
Move Sew Tool: Fixed issues occurring with multi-UV channels.
Hotspot Layout: Automatically arranges UVs of selected faces based on predefined layouts or applies UV layouts to unwrapped faces during building.
Modeling Mode
Separate Parts Tool: Creates new objects by separating unconnected parts of the selected object.
Follow Tool: Generates new 3D models by moving a profile (face) along a specified path.
Rigging Mode
Human Avatar Tool: Adds a tool to configure human-type avatars by adding an Animator to the Animation Root and linking it with a humanoid avatar.
UVEditor
Multiple UV Channels: Allows editing UVs on channels other than channel 0, requiring activation after selection.
Delete UMX Component: Removes UMX Components from the current scene, prefabs, or selected objects.
Improvements
General
Gameobject: Naming rules for new objects and modifiers now follow Unity's conventions.
Object Menu: Right-clicking in the hierarchy window provides access to UModelerX object creation via 3D Object > UModelerX.
Preferences: Options split into Editable Mesh, Modeling, and Rigging. Added new settings like saving mesh data in the scene folder and a Hotspot Editor.
Export: Faster export times and uses a period (.) as the decimal separator.
Modeling Mode
DisplayMode: Xray Mode merged into Display Mode with a new Checkered Mode that changes materials to checkered patterns.
Rigging Mode
Overlay Animation: Displays animations overlayed on the current bone structure.
Symmetry Mode (Bone Only): Allows mirrored selection and control for bones with matching names, excluding "Left" or "Right".
Rigging Tool Groups: Divided into Weight Group (vertex weight editing) and Bone Group (bone-related functions).
Weight Mirror Tool: Automatically identifies and mirrors bone weights using keywords like L, R, Left, and Right.
UI
Commentary: Warning logs are no longer displayed.
EdMeshInfo: SceneView's EdMeshInfo Panel is smaller with customizable info toggles.
UMX Setting Toolbar: Toolbar added for SceneView (Unity 2021.1+) or a button for older versions.
Others
Line Tool moved to Add Group and renamed Knife Tool.
Bug Fixes
Fixed issues where UModelerize failed on certain models and Mirror Modifier did not build during object duplication.
