Inflate Brush
From ZBrush Info
Inflat: In contrast to the Std brush, which pulls or pushes geometry along the normal of the surface under the center of the brush, Inflat expands geometry by pushing vertices along their own normals. This can be particularly important when you are doing sculpts that displace the surface a large amount with just one or two strokes.
- On the left of the image, creating spikes with the Std brush; on the right, the Inflat brush.
- In both cases, the all spikes were generated at the same time, with a single motion using the Spray stroke.
- Inflat spikes are perpendicular to underlying surface, Std spikes are all in the same direction.
