The following table lists common problems related to sculpting and possible solutions:
| Problem/Error Message | Possible Solution |
|---|---|
The cursor outline indicating the radius for the sculpt or paint tool disappears in the 3D View. |
The outline for the sculpt/paint tool cursor only appears when the tool is over the model in the 3D View. Position the cursor over the model to view it. The Radius property is set too large and the outline appears outside of the current 3D View. This can occur when setting the Radius using the B hotkey if the tool cursor is off the model. For more information, see Sculpt Tool properties. |
Sculpt on a model and the stroke doesn’t appear. |
The resolution of the model is too coarse in comparison to the size of the current sculpt tool. Add more subdivision levels to increase the model’s resolution or increase the radius of the tool. The Strength property is set too low for the sculpt tool. Increase the Strength and stroke again. If you’re sculpting using layers, ensure that the Opacity setting for the current sculpt layer is not set too low or to zero. For more information, see Sculpt Tool properties. |
Two sculpt tool cursors appear on the surface of the model when sculpting. |
The Mirror property for the tool is turned on. If you don’t want to sculpt in a symmetrical fashion, turn off the MIrror property. For more information, see Sculpt Tool properties. |
Sculpting causes large spike effects to appear on the model. |
The Strength property is set too high in relation to the current sculpt tool radius. Undo your stroke (Ctrl + Z), reduce the Strength property for the sculpt tool and try again. For more information, see Sculpt Tool properties. |
Symmetry property has no effect when sculpting. |
An incorrect mirror axis is specified. Check the mirror axis property and reset as required. If the model was moved off the XYZ origin, some mirror axis properties will not work. Use the Local or Tangent mirror properties in these situations. For more information, see Sculpt using tool symmetry. |
Sculpting on a model using a stencil with the Mirror property turned on produces unexpected results. |
When the Mirror property is turned on and you sculpt through a stencil, different areas of the stencil image affect opposite sides of the model. As a result, the sculpting will most likely not appear symmetrical. A better approach is to create a sculpt layer, apply sculpting to the layer through the stencil, then duplicate the layer and mirror it across the axis of symmetry. For more information, see Sculpt using layer symmetry. |
A semi-transparent 2D image appears in front of the model in the 3D View. |
You may have a stencil image selected for the camera view. In the Stencil tray, click the Off button. |
Cannot undo sculpting performed on another subdivision level after switching levels. |
The Undo history is not saved when switching between subdivision levels. You can only undo sculpting made to the current subdivision level. |
Sculpting performance decreases at higher subdivision levels. |
Sculpting at higher subdivision levels (when many vertices are modified by a particular sized brush) requires more RAM than on a lower subdivision level (using the same sized brush) because fewer vertices are affected. In general, make changes that affect larger regions of a surface at a lower subdivision level. Fewer vertices have to be moved as a result and sculpt performance is improved. |
