The Paint Effects Tool goes beyond traditional paint software by allowing you to paint directly in 3D space, either on the ground plane or on an object’s surface. When you use Paint Effects for 3D work, the paint strokes are three-dimensional and editable.
With Paint Effects, all of the hundreds of preset brushes found in the Visor under the Paint Effects tab (airbrushes, pens, markers, watercolors, plants, fire, metal, flowers, trees, and underwater etc.) can be used to create 3D objects in your scene. For example, you can use the preset plant brushes to paint a 3D tropical fern garden around a walking character in your scene.
An electronic tablet with stylus is an ideal tool for painting with Paint Effects. With a real paint brush, pressing harder makes the brush wider and applies the paint more thickly. You can achieve the same effect with Paint Effects by specifying the effect of pressure on the stylus for each stroke and the threshold of response to pressure. You can map up to three attribute values to stylus pressure and edit them as you work.
