Shift Options Panel

This panel, which floats by default, opens when any Shift tool is active, and provides settings for modifying its effects.

• Ribbon > Freeform tab > Paint Deform panel > Enable Shift tool.

Interface

Floating Shift Options panel

Full Strength

The size of the brush center area (white circle), where the Strength % setting is fully applied.

Vertices outside the Full Strength circle but within the Falloff circle (see following) move at a gradually slower rate.

To adjust Full Strength interactively, use +drag.

Falloff

The size of the brush outer range (black circle), where the Strength % setting gradually decreases from full strength to zero.

To adjust Falloff interactively, use +drag.

Mirror

When on, the Shift tool effect is applied equally to both sides of an object across the mirror axis, as specified by the Mirror Axis setting (see following).

Note: When the ribbon is maximized or the Shift Options panel floats, the following controls appear on the Shift Options panel expansion.

Strength %

The overall rate at which the Shift tool deforms an object. For subtler effects, lower the Strength % value.

To adjust Strength % interactively, use ++drag.

Brush Affects

Determines the shape of the volume the Shift brush reshapes:

• Depth The brush affects a cylindrical volume created by projecting the radius through the poly object.
• Spherical Radius The brush affects a spherical volume; thus its effect is typically less than that obtained with the Depth setting.

Use Selected Verts

When on, the Shift tool affects selected vertices only. Applies at the object level and all sub-object levels.

When off (the default), the Shift tool affects all vertices in the selected object.

Ignore Backfacing

When on, the Shift tool affects only vertices facing you.

When off (the default), the Shift tool affects all vertices in the selected object within the Falloff range, regardless of their visibility or facing.

Mirror Axis X/Y/Z

Choose the axis across which the Shift tool is mirrored (see Mirror, preceding). This setting uses the World coordinate system.

Freeze Axis X/Y/Z

Click these buttons to activate any combination of X, Y, and Z. When an axis button is on, the Shift tool is prevented from moving vertices on the object’s corresponding local axis.

Tip: To limit the Shift tool’s effect to a particular axis, turn on Freeze Axis for the other two axes.

Freeze Selected Edges X/Y/Z

Click these buttons to activate any combination of X, Y, and Z. When an axis button is on, the Shift tool is prevented from moving selected edges on the object’s corresponding local axis. Unselected edges move freely.

Applies at all sub-object levels.

For example, to allow Shift to cause vertical deformation only on the upper half of an object, first access the Edge sub-object level and select the upper half of the object, turn on Freeze Selected Edges X and Y, and activate the Shift tool. Then, at the object level or at any sub-object level, using Shift on the upper half of the object prevents horizontal deformation.
