Vertex Editing allows you to change the shape of a brush by moving its vertices that define the shape.
Select camera mode from the toolbox
- Select a brush
- Hold down the CTRL key use the Left Mouse Button (LMB) on a vertex. A red cross appears on that vertex. This is the pivot.
- Hold down ALT + and drag the LMB.
Select vertex edit mode from the toolbox.
- Select one or more brushes. The red builder brush can be selected too.
Hold either ALT-Gr or CTRL + ALT, click in empty space in an 2D UnrealEd Viewport and drag a marquee selection rectangle around the vertices you wish to select.
When you release, the boxes on selected vertices turn white.
- CTRL-click on any of the white-highlighted vertices and drag to move them. Be careful not to start the click & drag too close to another brush, or that will become selected too.
To add vertices to the current selection, repeat the procedure, holding SHIFT as well, ie CTRL+SHIFT+ALT or SHIFT+ALT-Gr.
- Camera mode allows only one vertex to be moved at a time.
- Vertex Edit mode allows the rectangular marquee to select multiple vertices.
Because the 2D UnrealEd Viewport cannot display depth, sometimes your brush will only show one vertex where 2 or more exist in 3D space. This can be demonstrated with a cube. Choose the right mode depending if you want to move one or more stacked vertices.
- Camera mode selects only one vertex
- Vertex Edit mode selects all stacked vertices
- At 16 grid units or lower, dragging vertices zip around too fast
- At 64 grid units or higher, dragging vertices feel sticky
- Therefore, 32 or 16 is best.
- Brushes can occasionally 'break' when vertex editing. The cause for this is unknown but the effect will likely result in a BSP Hole.
- UnrealEd Interface is the main reference for the interface in general
- Moving vertices is usually done in one of the 2D UnrealEd Viewports
- Toolbox covers all the buttons down the left-hand side of the UnrealEd window
- See Mouse Control for more information on mouse actions in different modes.
Sobiwan: I still cant figure out what "Alt-gr" is. Anyone?
Tarquin: "Alt-gr is the right-hand Alt key on European keyboards.
