Sculpt with clay
Build up or remove surface volume with a brush stroke. This simplified height-field example shows a clay-like raised strip.
Before you start
Open Sculpting with a mesh that has enough surface geometry for the desired detail. These brushes move existing vertices; they do not automatically add resolution.
Use the operation
Build up a local form with short clay-like strokes.
- Choose Clay from the brush selector in the Sculpting sidebar or settings panel.
- Set a moderate brush size and low intensity. Drag across a small area of the mesh to establish the form.
- Build the form in several short strokes, rotating the view between passes. Use Invert when you want the opposite displacement.
Controls and choices
| Controls | What changes |
|---|---|
| Brush size | Controls the affected region relative to the scene’s measured size. A small brush cannot create detail if too few vertices lie beneath it. |
| Intensity | Controls stroke strength. Lower values and repeated passes provide more gradual control. |
| Clay behavior | The brush combines local displacement with a plane-based effect. It changes geometry, unlike painting color onto a texture. |

Check the result
Check the silhouette and nearby thin surfaces, not just the lit patch. Undo an overly strong stroke and reduce intensity before continuing.
