Sculpt along normals
Displace the brush region along its sampled surface normal. The surrounding region stays fixed.
Before you start
Open Sculpting on a mesh with adequate density. The brush used for this operation is labeled Normal in the current Show3D interface.
Use the operation
Raise or push back a local region using the brush area’s normal direction.
- Choose Normal in the brush selector.
- Set a low intensity, then make a short stroke over the region to raise.
- Enable Invert to reverse the displacement. Inspect from a side view so you can judge the height change.
Controls and choices
| Controls | What changes |
|---|---|
| Normal direction | The brush displaces the affected region along an averaged local normal. It is not a uniform thickness or shell-generation operation. |
| Size and intensity | Size sets the working area and intensity sets the strength. Start with a region wider than a single sparse polygon. |
| Invert | Reverses the displacement so the same brush can push inward. Inspect thin walls before making repeated inward strokes. |

Check the result
Confirm the height and transition match your intent and that the surface does not cross a nearby wall. Use Clay for a different buildup effect or Flatten to reduce unevenness.
