What Does Depth Tab Under Brush Menu Do

To demonstrate the effects of this black dot and white circle,

Let me increase the thickness of the belt which means the Z intensity to 50.

Lightly tap on the belt, lightly so that I don’t accidentally move it.

Now the thickness is equally distributed, inside and outside the skin surface.

Let’s use the Depth tab to pull the belt out of the skin! Sounds dramatic!

Increase the imbed by clicking and dragging upwards on the white circle or black dot.

Once again, lightly tap on the red curve line to update the strap.

See how it is raised above the skin surface? Just like the image on the Depth tab?
