Subdivision surface levels

Next, you refine the shape of the fingers by working in Standard Mode. In Standard Mode, you can make edits to mesh vertices, edges, or faces at different levels of refinement, that are not possible in Polygon Proxy mode. The different levels of refinement are referred to as subdivision surface levels.

To refine the fingers using subdivision surface levels

1. Select LeftHand.
2. Select the Surfaces menu set.
3. Select Subdiv Surfaces > Standard Mode. This switches to a mode that lets you modify the surface at various levels of detail to suit your needs.
4. In the scene view, right-click LeftHand and select Vertex from the marking menu.
   

   This displays 0s on the surface in the same positions as the vertices in Polygon Proxy mode. In fact, the 0s are vertices.

   The number 0 refers to the level of detail you are capable of editing. The 0 level is identical to the coarse control possible in Polygon Proxy mode by manipulating the vertices. You can move, rotate, and scale the 0s to alter the shape of the surface just as you did for vertices in Polygon Proxy mode.

   Note

   If numbers do not appear on the hand, open your preferences (Window > Settings/Preferences > Preferences). In the Display > Subdivs section, set Component Display to Numbers.

5. Right-click the surface and select Display Level > 1.

   Though the 1s are displayed in the same regions as the 0s were previously, there are many more 1s displayed. The 1s are also vertices, and their increased presence means you can refine the shape with more subtlety.

6. Refine the shape of the fingers, thumb, and hand as desired by selecting various level 1 vertices and moving, scaling, and rotating them with the transformation tools. (Scaling and rotating has effect only if you select two or more vertices.)

   It’s essential to tumble the camera from various perspectives to make sure you’ve selected only the desired vertices.

   

   To return to level 0 to alter the shape with fewer vertices, right-click the surface and select Display Level > 0. Each level has advantages. Level 1 allows finer control because there are more vertices. Level 0 allows control of broader regions, and it’s often easier to select the desired vertices since there are fewer of them. It’s common to switch back and forth between levels repeatedly in a work session.

   The hand has level 2 vertices at various locations, for instance, at the webbing between the fingers. You can also work at that level of detail if desired (select Display Level > 2).
