Vertex / Edge / Polygon / Object ¶
There are 4 types of elements you can select and transform.
I think these tools are used most frequently in UModeler so they are located at the top of the scene view. Firstly let me explain the Object Tool. With this tool you can select other objects, and move/rotate/scale them, which is same as Unity Object Mode.
Now let’s see Vertex Tool, Edge Tool and Polygon Tool.
A mesh consists of vertices, edges and polygons. We call them elements.
And there are gizmos which are displayed on the center of the selected elements and used for moving, rotating and scaling elements. They look like the following image roughly.
You can select vertices and move/rotate/scale them with the Vertex Tool. The Edge Tool can make you select edges and move/rotate/scale them. Using the Polygon tool, polygons can be selected and moved/rotated/scaled.
When you rotate and scale elements, the pivot position is usually the center of them. But when the 3D cursor is on, the cursor posision will be the pivot position.
Basically selection of each element can be done by placing the mouse cursor there and pressing
LMB dragging from an empty space will draw a rectangle and select elements inside the rectangle.
LMBon an element.
Rchanges the current gizmo like Unity.
SHIFTwhile dragging a gizmo, the selected elements are extruded.
CTRLwhile dragging the move gizmo and moving to another vertex, the selected elements’ selected axis’s value will be snapped to the vertex. This is called
CTRLwhile dragging a gizmo, the vertices consisting of the elements will be split.
LMB Double clickon a polygon will unwrap and stick it. This is called
Auto Layout. Click here to get more infor about it.
Moving the selected vertices/edges/polygons holding
V allows their pivot position to be snapped to a vertex under the mouse cursor.
- Select Only Visible
If on, Selects only visible vertices/edges/polygons from a camera. Occluded elements from other polygons will not be selected. This is available only when the game object has MeshCollider component.
How distant the selected elements move. This is only available as translation gizmo is enabled.
- Snap To Polygon
An edge is snapped to a close polygon within a specific distance. This is only available as the edge is being translated.
- Snap To Vertex
A vertex is snapped to the other close vertex within a specific distance. This is only available as the vertex is being translated.
- Move To Cursor
Moves the current selected elements to the 3D cursor position.
- Insert Vertex
Inserts a vertex to an adjacent edge to avoid T-junction.
