How do you make the brush like the brush in the Demohead where what u do on one side automatically happens to the other?
The Cloner brush is a 2.5D brush. That means that to use it on a model you need to use Projection Master. To put what you do on both sides of your model, you need to rotate the view to the side before dropping with Projection Master and then also make sure that PM’s Double Sided setting is active.
