Sculpt Layers
Every stroke records into the active layer. The stack starts empty, so sculpting waits until you add one.
Every stroke you make records into a layer in the Sculpt Layers stack, in the Details panel. The stack is per node.
The stack starts empty, and sculpting is refused until you add a layer. Selecting a fresh Sculpt Mesh node opens a new layer session with nothing in it. Try to sculpt before adding one and you get the toast "No active sculpt layer - add or select a layer in the Layers panel to sculpt." instead of a stroke. Mask painting is not affected by this gate and works with zero layers - it is a selection, not a content edit.
The panel's empty state spells out the same thing: "No layers - sculpting is disabled. Add a layer to start sculpting (every stroke records into the active layer; per-layer strength, visibility, delete)."
Buttons
| Button / control | Tooltip |
|---|---|
| + | "Add a new layer (it becomes the recording layer)" |
| Dup | "Duplicate the active layer" |
| Merge | "Merge the active layer into the one below it (bakes both at their current strength)" |
| Del | "Delete the active layer (its sculpting is removed from the surface; undoable)" |
| eye icon | "Show/hide this layer's contribution. Hiding the recording layer hands recording to the nearest visible layer." |
| row / name | "Click the row to make this the recording layer; double-click the name to rename" |
| opacity slider | "Layer strength 0..1 - applies live on every layer, the recording one included" |
New layers are auto-named "Layer N". The recording layer is whichever one you last clicked (or duplicated, or added) - every stroke goes into that one until you click a different row.
Sculpt layers do not have blend modes - that control belongs to paint layers only.
Saving
The whole stack - every layer, its strength and its visibility - is written into the node when you press Accept, and is restored the next time you select the node and reactivate the tool.
