The ear is certainly one of the most delicate part of the human body, and it will be one of hardest to sculpt. For it, you need a closer look at the sculpting brushes parameters. These are (almost) all grouped together in the Brush Palette.
The Edit Curve determines, and can modify, the brush profile. To get a brush profile that mimic the Edit curve, activate the Accucurve tool. The Accucurve tool is also a quick way to switch from a rounded brush to a sharper one. It's a clever idea to have this button on your interface. Selecting an Alpha in the Alpha palette will also have a great impact on the brush look.
The circumference of the ear, the Helix, with its part bent back on itself is certainly the most difficult to be sculpted.
For it, we are going to use the Gravity tool, in the Brush Palette.
Set the Gravity orientation gizmo to the right, and the strength to 100, and draw a first stroke to shape the recess.
Hold Alt and draw a second stroke to shape the fold. When you reverse the Stroke direction with Alt, the gravity is also inverted..
Put the model in a view of three quarter, and use the Snakehook brush to shape the auditory canal.
Use the Clay and the Flatten Brushes with a low intensity to build up the earlobe, then the Move brush to highlight it with regard to the head. The Flatten brush will also help you to create a sharp transition between the circumference of the ear and the head.
The Samples parameter, which you can find in the Brush Palette, has a great deal of importance. This can change the sensitivity of the Clay and Flatten brushes, by averaging the orientation and height of the underneath surface.
To be able to draw very precise and controlled brush strokes with ease is going to make you win a great deal of time.
To do it, the Lazymouse tool will help you a lot. Open the Stroke menu, activate the tool, and set the LazyStep to 0.03.
A digital red string is now attached between your cursor and the brush itself, and sculpting can continue.
