Sculpt meshes

Use the Sculpt option to change the shape of a mesh:

1. Select the mesh.
2. Click Mesh Tools tab > Triangles panel > Sculpt to display the Sculpting toolbar:

   

3. Select one of the following operations:
   • — to add material. Use this option in combination with the brush tools, to add material. Using Add material does not increase the number of triangles, but lifts the existing nodes. The orientation of the model affects the way the area is built up.
   • — to remove material. Use this option in combination with the brush tools, to lower the triangle nodes under the brush, to make it look as though material has been carved out of the model.
   • — to smooth triangles. Use this option to smooth out irregularities in the triangle nodes. For each node in the smoothing area, PowerShape calculates a position based on the surrounding nodes.
   • — to erase triangles. Use this option to undo add, remove or smooth actions made during the current editing session. You can use it in combination with Strength to undo changes; set Strength to 100% to move the node to its original position in one step. Set the option to 50% to move the node to its original position in two steps.
4. Use the following to adjust the brush:

   Brush diameter — Select the button and drag the slider (or D + mouse scroll wheel) to increase or decrease the size of the brush.

   Strength — Select the button and drag the slider (or H + mouse scroll wheel) to increase or decrease the amount each node is raised or lowered as a percentage of the brush radius.

   Brush Smoothness — Select the button and use the slider (or M + mouse scroll wheel) to increase or decrease the smoothness of the area you are sculpting. The smoothness determines whether there is any reduction in the strength towards the edges of the brush.

   A setting of 0% maintains full strength right to the edge of the brush.

   A setting of 100% smooths the material across the diameter of the brush.

   Use the slider to enter the value to be associated with the button you have selected.

5. Use the following to specify maximum deviation and length:

   Limit deviation — Select the button and enter the maximum deviation that the nodes can move.

   Refine triangles — Select the button and enter the maximum length to be used when refining triangles.

   Show deviations — Select this button to see the difference between the original and sculpted models when using the editing tools. Deselect it to hide the differences.

6. Move the cursor over the model to make the required changes. When you have finished editing, click the Exit button to close the toolbar.
