Adds a new control to Blender that allows you to adjust normals by stroking your model with a brush.
Once you install the tool, a new panel will be added to the 'N' menu on the right side of your viewport under the Kitfox tab.
[
The Normal Brush submenu contains controls for the brush. To begin, select the object you want to adjust normals on and then click the Start Normal Tool button to activate the brush. The normals of the object will then be shown overlaid on the mesh and you can click and drag with the brush to adjust them.
Adjust the strength of the brush stroke.
Change the display size normals are drawn in the overlay.
Radius of the normal brush. You can also press the [ and ] keys to change the size.
If checked, your brush stroke will only affect faces facing the viewer. Otherwise, all vertices within a sphere the size of the brush are affected.
- Fixed - Brush stroke will paint all normals to point in a single direction.
- Attract - Normals will point toward origin of selected target object.
- Repel - Normals will point away from origin of selected target object.
- Vertex - Paint normals to reflect the underlying geometry. This effectively 'erases' your tweaks.
In Fixed mode, indicates the direction of the normal you are painting. You can set it directly by typing in the normal or select Exact Normal to get a trackball you can use to adjust the normal. You can also click the Pick Normal button to get an eyedropper to pick the normal from another piece of geometry in the scene.
In Attract and Repel modes, indicates the target objects that normals will point toward/away from.
Also included under the Fix Seam Normals menu is a control to automatically copy normals across seams. Simply select two or more objects with edges that meet. Then press the Copy Seam Normals button. The normals from the active object will be copied to the other selected objects wherever the selected object' vertex is snapped to the same spot as the active object's vertex.
To build, execute the makeDeploy.py script in the root of the project. It will create a directory called deploy that contains a zip file containing the addon.
To install, start Blender and select Edit > Preferences from the menubar. Select the Add-ons tab and then press the Install button. Browse to the .zip file that you built and select it. Finally, tick the checkbox next to Add Mesh: Normal Brush.
This addon is under review and will soon be distributed on the Blender market.
