- In Post, open the relevant .MCP file and ensure that the required solving skeleton is selected in the Current Subject field.
To check that no target skeleton has been imported, open the Subject Management panel.
The Retargeting column displays a red circle, indicating that no retargeting setup is present.
For more information on the Subject Management panel, watch Vicon Shogun 1.3 Post Tutorial - Subject Management on YouTube.- Do either of the following:
- In the Subject Setup panel, select the Retargeting tab, select Load and then select the required target.
Or - Drag the target skeleton file into the Shogun Post view pane.
When you are prompted, choose Skeleton.

- In the Subject Setup panel, select the Retargeting tab, select Load and then select the required target.

Hide any unnecessary joints. To do this, select the bone, and in the Attributes panel, clear the Showing box.
On the Retargeting tab, select Map Mode (see About map mode) to enable this mode.
This creates a separate clip that you use to pose the target skeleton relative to the source skeleton.
In the Target Skeleton Setup section, in the list of bones, find the bone that is the root, then right-click and select Set Root. This ensures the root has six DoFs and any bones above it have zero DoFs.
Confirm the target skeleton's DoFs were imported or set them as required.
If the source and target skeletons don’t have roots in the same position or have a differing orientation, select Align Skeletons.
Shogun Post tries to put the skeletons into the same positions and root pose.
You can more closely align the skeletons using the Translate and Rotate manipulators (not the Special manipulator).
Be sure to move the root, not any dummy bones above it.
If you need to globally scale the target skeleton to be the same size as the source skeleton, on the Retargeting tab, change the Target Scale value. Ensure that the ankles and clavicles in the target and source skeletons match.
...
In the lists on the right of the Retargeting tab (or anywhere else in Shogun Post), select a matching source and target bone, then click Add Position or Add Rotation to create a constraint between them. The order of selection does not matter.
As a starting point for the constraints, add a position on hands, feet and hips; and rotation on all joints.
If your target skeleton has more joints than the Vicon source skeleton, you can constrain multiple target joints to the same Vicon source joint.

Tip: You can use HSL scripting to speed up creating constraints. For information and examples, see attach in HSL scripting with Vicon Shogun.Another way to speed things up is to mirror the changes you make to one side of the source and target skeletons onto the other side. See Mirror constraints and Mirror joint manipulation.
You can alter multiple constraint weights in the table on the Retargeting tab.
To enable you to immediately see the changes you're making, in the toolbar at the top, ensure the Enable interactive retargeting button
is selected (green).You can also select or clear Active to turn constraints on or off.
To check targets, ensure that the View Filters option for Constraints (for Retarget) is selected.
Set weights for all rotations. The recommended value for Rotation weights is 200. To set multiple rotations to 200, on the Retargeting tab, drag to select the required rows in the table and then in the Weight column, set the value of one of them to 200.
All the selected rotation weights are updated to 200.
Scroll pagebreak Tip: If you want to automatically copy your changes to weights from one side of the skeleton to the other, ensure the Mirror Weight Changes option is also selected (see Mirror weights).- To add keys, select the relevant line(s), right-click and select Set Key.
To fine-tune keyframes, you can use the controls in the Graph view. For example, you can use the right-click (context) menu in the Graph view to to cut or insert sparse keys. You can also change the time of a key by clicking and dragging on the Graph view. To save the VSR mapping file, at the top right of the Retargeting tab, click the Save button.
By default, VSR files are saved to C:\Users\Public\Documents\Vicon\Retargets.

The same option enables you to mirror edits to retargeting constraints.

When you're adding or editing weights, you can use the mirroring option, Mirror Weight Changes. to make the same changes on both sides of the skeleton simultaneously.
