Using Shift and CtrlOption Keys

• What is Meridian Tapping and How Can It Help

The previous exercise involved the use of "mass-painting" keys - Shift and Ctrl/Option. As you've seen, Shift paints all faces that have the same material as the selected face. The Ctrl/Option key will paint the selected face plus all faces that are connected to it.

1. Start with a form like this.

2. Pick a material and use either Shift or Ctrl/Option to select one face, which paints the entire form.

In this case, both keys produce the same result. All the unpainted faces are contiguous and are therefore painted.

3. Undo, and pick a different material. Apply it to the horizontal face shown.

4. Go back the previous material, press Shift, and click the vertical face shown. This paints all faces that have the same material as the selected face (in this case, the default, unpainted material). If there were other forms that had unpainted faces, these would be painted as well.

5. Undo, and use Ctrl/Option to paint the same face. only the faces above the already-painted face are painted.

This is because these top unpainted faces are not contiguous to the bottom unpainted faces - the continuity is broken by the painted horizontal face.
