Modes define how a brush interacts with a mesh. Some move vertices around, others apply values per-vertex (like color).

• To enter a Brush Mode click on the toolbar button.
• To exit a Brush Mode, click on the active mode button, or select any standard Unity tool (ie, Move, Rotate, Scale)

You can tell if a Brush Mode is on by it's button in the toolbar- the active mode will appear with a dark blue accent. For example, the Smoothing Mode is activated in the below image:

The available modes are:

	Mode Name	Description

	Smooth	Smooth the differences between vertex positions.
