4. Brush

I assume you have built some masks to isolate your drawing areas.

Now let's do some depth map drawing.

Brush

There are currently 3 type of brushes for depth value drawing.

Pen Brush

It adds or subtract depth values on to the area where your brush came across.

Roller Brush

It sets the depth values to a fixed value on to the area where your brush came across.

Smooth Brush

It averages nearby pixels' depth value on to the area where your brush came across.

p.s. currently the smoothness value is fixed and the slider has no effect.

Brush size

For all three brush types, you can change you brush size by using the slider.

You can also hold CTRL + scroll up or down using your scrollwheel to change brush size.

For advanced user

Depth values are stored in RED channel of a 24 bit depth map PNG.
