Drawing Face Sets in Blender allows you to define distinct areas on your mesh, primarily for sculpting and selection purposes. This is typically done using specialized tools within the Sculpting workspace.
Drawing Face Sets is achieved through a simple stroke action, with additional control offered by modifier keys.
The Basic Drawing Action
To draw Face Sets, you use a brush-like tool. With each stroke you make on the mesh:
- You will draw new Face Sets in areas that previously did not have them assigned by this method.
- You can also extend existing Face Sets by drawing over areas already assigned to a Face Set.
Using Modifier Keys for Control
Blender provides modifier keys to alter the behavior of the Face Set drawing stroke, giving you more control over the shape and flow of your Face Sets.
- Holding Ctrl Key: When you hold down the Ctrl key while drawing, the stroke will continue drawing the same face set as the one located directly under the cursor when you started the stroke. This is useful for expanding a specific Face Set without creating new ones or blending into adjacent ones.
- Holding Shift Key: Holding the Shift key activates a smoothing or relaxing effect on the Face Set edges. This action will relax or smooth the edges of the Face Sets. It achieves this by modifying the underlying topology of the mesh so that the edges of the Face Sets flow more smoothly and naturally along the perimeter of the defined areas.
By combining the basic stroke with these modifier keys, you can efficiently define, refine, and organize areas on your mesh using Face Sets for various sculpting and modeling tasks.
