The Displacement Brush (D Brush) paints displacement pixels to Displacement layers. Once painted the displacement pixels are converted to normals.
The D Brush controls are shown on the left and described below.
Flow Interval - The interval in mouse distance moved as a percentage of brush size before a paint event occurs.
Height - Modifies the height of the brush. Value can be negative to invert the brush shape.
Hardness - The lower the value the more blur is applied to the brush.
Size - The size of the brush in pixels.
Tile Paint - If checked the paint events will tile over the edges of the canvas.
Surface Curve - If enabled the curve defines the surface of the brush from outside to inside. If not enabled the brush displacement is used. Linear and curved knots can be added
and deleted. Right click on a knot to change its type.
Brush Grid - Displays the current brushes for the selected brush library.
Add Brush - Opens a file dialog. Select a displacement image to turn into a brush. The brush will be added to the current selected library. All brushes are stored in the folder
C:\Users\<USER>\Documents\ShaderMap\SM3\Libs\DBrush D Brush files have the extension .smdb. To create a new library simply create a new folder in the DBrush folder and put brush files in it.
Delete Brush - Deletes the brush file from the library folder.
Library List - Selecting a brush library displays its brushes in the brush grid.
Displacement layers have both displacement and rasterized normals in them. Use the View Disp checkbox found on the Layer Panel to enable displacement preview on the canvas.
