The points that we wish to duplicate and mirror.

The name of the attribute which will be created to contain the mirroring information. This will be a dictionary attribute containing the following keys:

{
    'reference': "ptnum" or the name of the attribute to reference (e.g. "name"),
    'value':     The value of the attribute specified in the 'reference' key or the point number of the mirrored point if 'reference' is "ptnum",
    'flipaxes':  An integer value that stores how the points were mirrored (__By Scale__ or __By Rotation__)
}

The attribute whose value will be used to match the mirrored points by any downstream operations that support mirroring. The value entered here will be stored under the Point Mirror Attrib ['reference'] key. If left blank the point number will be used.

A list of point attributes in the input geometry to transform when the mirrored points are created, note that the attributes will be transformed consistently with the mirroring operation - i.e. if the points to be mirrored contain a normal attribute aligned with the joints Y-axis then the normal on the newly created joints will still align with the Y-axis of those new joints, regardless of which Mirroring Style has been used.

If enabled any point groups listed on the input geometry will be copied over as part of the mirroring operation. The groups can also be renamed according to the patterns supplied in Group Rename and Group New Name parameters.

For example, if the skeleton has point groups L_arm and L_leg, setting Group Rename to L_* and New Group Name to R_* will add any mirrored points belonging to those groups to new groups R_arm and R_leg respectively. Keeping the Group Rename and New Group Name patterns to the default * will simply keep the group names the same.

A pattern to search for in the input group names, this will be replaced with the pattern supplied in New Group Name when creating any mirrored group.

A pattern with which the Group Rename pattern will be replaced when creating any mirrored groups.

Where in the point name to look for the tokens specified by in Find Tokens. This will depend upon the naming scheme on the input, for example if the input names follow this kind of pattern:

left_upperarm, left_lowerarm, left_hand

Then we would set this to 'Start'. On the other hand, the following scheme would require this parameter to be set to 'End':

upperarm_left, lowerarm_left, hand_left

If Find Tokens is left blank then the first token specified in Replace Tokens will simply be added to the input point’s name at either the start or end.

A space separated sequence of tokens to look for at the position specified in Token Position in the input points' names. This will be replaced with the corresponding tokens in the sequence of tokens provided in Replace Tokens.

A space separated sequence of tokens to use as replacements for the tokens provided in Find Tokens.

This parameter sets how the transforms of the input points should be mirrored to the newly created points.

The direction in which to perform the mirroring operation. This is visualized as the normal of the plane presented in the viewport.

The origin of the plane used for mirroring.

When Reflect Using is set to Mirror Point, this is the point on the input that will be used to define the plane used for mirroring.

When Reflect Using is set to Mirror Point, this is the axis of the point specified in Reference Point that will be used as the normal of the mirroring plane.
