Puffing and Straightening Hair

There are times when you just need a little more volume in your hair, or you need to straighten it out. For example, after you comb the hair in a downward direction (negative Y), you may need to give a little lift (puff) to the roots at the scalp.

The two commands in the Puff menu on the Hair toolbar can help you with these styling issues.

To puff hair at the roots

Select some hair strands or points and choose Puff At Root on the Hair panel.

As you drag the mouse, the hair straightens (puffs) out starting at the root, moving it away from the emitter object's surface. The farther you drag, the more the points are straightened.

To straighten hairs

Select some hair strands or points and choose Puff Stand on End on the Hair panel.

As you drag the mouse, the hair straightens out, starting at the tip. The further you drag, the more the points are straightened.

For either of these Puff operators, you can change the amount of straightening that happens by setting the Puff Factor in the Hair Puff property editor. A value of 0 results in no change, and 1 results in completely straight hairs.

You can animate the Puff Factor to create movement on the hair; however, if you do this, you cannot use dynamics on the hair.
