Pose Symmetry

Pose symmetry mirrors pose-bone transforms from Blender-style left/right bone names. It works on an active armature in Pose Mode and does not require a mesh config.

Where to Find It

In the 3D View sidebar, open:

OmniMirror > Pose

Pose Transforms

Under All Bones:, set Flow and Influence, then click Symmetrize All Bones.

• Average averages each left/right pose pair.

• Left -> Right copies the left pose to the right bone.

• Right -> Left copies the right pose to the left bone.

• Influence blends the current target pose toward the mirrored result. At 1.0, the mirrored result is applied fully.

Under Selected Bones:, select one or more source bones and use:

• From Selected to copy selected bones to their mirrored counterparts.

• To Selected to copy each counterpart to the selected bone.

If both bones of a pair are selected, the transform action averages that pair. Bones without a Blender-recognized left/right counterpart are skipped.

Constraints (Experimental)

The Constraints: actions mirror the constraint stack for selected source bones:

• From Selected replaces the counterpart bone’s entire constraint stack with mirrored copies of the selected bone’s stack.

• To Selected replaces the selected bone’s entire constraint stack with mirrored copies of its counterpart’s stack.

Armature subtargets use Blender’s standard left/right name flipping. Selecting both bones of a pair skips that pair.

Important

Constraint symmetrization is experimental and replaces the target bone’s entire constraint stack. Review the result before relying on a complex rig.

Reviewed Constraints

The following constraints have been reviewed in the order shown in Blender’s constraint menu:

Constraint	Mirrored behavior
Copy Location	Copied unchanged.
Copy Rotation	Copied unchanged.
Copy Scale	Copied unchanged.
Copy Transforms	Copied unchanged.
Limit Distance	Copied unchanged; it does not need a symmetry-specific range conversion.
Limit Location	The X range is inverted: target min_x = -source max_x and target max_x = -source min_x.
Limit Rotation	The X range is copied. The Y and Z ranges are inverted.
Limit Scale	Copied unchanged.
Maintain Volume	Copied unchanged.
Transformation	Location X ranges are inverted; rotation Y and Z ranges are inverted; scale ranges are copied. This applies to both From and To ranges.
Transform Cache	Not copied. OmniMirror reports a warning.

Other constraint types are copied with their writable settings and mirrored armature subtargets, but do not yet have reviewed type-specific axis or range conversion.
