[new zBrush 4 Videos - really strong features]

The Shadow Box is the same as 3DCoat 's Sketch Tool that we have since many many months.

But what is great is Pixologic made it interactive using live masks instead of imported images.

While in 3DCoat we need to make our mask in an external 2d app and its harder to make good matching Top/side/front images.

You can also use imported images in shadowbox, painted by spotlight and then mask by intensity/saturation etc, then draw on the other planes to achieve shape.
