After you have captured a wand wave, set the volume origin and axes so the cameras and volume in Shogun Live reflect the actual positions of the cameras in relation to the capture volume, (as well as to each other).

1. To see the axes in relation to the volume, in the **Workspace**, change the view to **3D View**.
2. Place the calibration device on the capture volume floor in the position you want the volume origin to be and in the orientation you want the axes to be (reflected in the axes displayed in the **3D View**). Typically, this calibration device is an Active Wand.

3. In the **Camera Calibration** panel, go to the **Volume Setup** section, display the Advanced properties > Macro (inline-media-image)

 and in the wand list, ensure the appropriate Active Wand is selected.  
:check_mark: **Tip**: If you're working in a Y-up coordinate system, select **Legacy Y-Up Scene Orientation.**
4. In the Volume Setup section, click **Start Set Origin**.
  After a few seconds, click **Set Origin**.
5. In the **3D View**, display the **View Filters** and in the **Volume** options, ensure that **Cameras** is selected.
6. In the **3D View**, **Perspective** view, all of the cameras shift as a group, so the origin of the capture volume is aligned with the wand.

### Set the origin with a custom L-frame

To improve calibration stability and consistency over time, you can use a custom L-frame to set the origin of your system.

As described in [Set the volume origin](https://vicon.atlassian.net/wiki/spaces/ShogunLive121/pages/2381449253/Set+the+volume+origin#SetVolOrigin), you can use a Vicon Active Wand to set up your volume coordinate system quickly and easily. However, using a larger, custom calibration object (in this case, markers embedded in the volume floor and/or wall) can improve calibration stability and consistency over time.

A typical way to use a custom L-frame would be to keep markers on a wall, hidden during camera masking, then when you're ready to set the coordinate system for your volume, make the markers visible and use the custom L-Frame as described in the following steps.

    **To create a custom L-frame:**


1. With the system calibrated, set the origin as normal (see [Set the volume origin](https://vicon.atlassian.net/wiki/spaces/ShogunLive121/pages/2381449253/Set+the+volume+origin#SetVolOrigin)), including setting the floor offset (see [Set the floor plane](https://vicon-help.atlassian.net/wiki/spaces/ShogunLive121/pages/1253212400)), as required.
2. Position a number of markers on the edge of the volume and select them.
3. In the **Tracking **panel (displayed as a tab on the right in the Default layout), click the **Setup** tab, go to the **Object** section and in the **Prop** field, enter a name for the custom L-frame then click **Create**.
  The new custom L-frame prop is displayed in the 3D View.
4. Pause the real time and in the **Tracking **panel on the right, select the prop you just created.
5. To display the Object Manipulator, press M. (For more information on the Object Manipulator, see [Move props](https://vicon-help.atlassian.net/wiki/spaces/ShogunLive121/pages/1253212208).) In the Workspace (3D View), the Object Manipulator is displayed.
6. Before exporting, you must reset the object's position. To do this:
  1. In the **Tracking** panel on the right, ensure that the custom L-frame is still selected.
  2. Set the Object Manipulator to Global .
  3. Change all the values to zero, so the origin matches that of the L-frame.
  4. Click the activated X, Y and Z buttons to reset the origin.
7. In the **Tracking** panel, with the custom L-Frame selected, right-click and then select **Export**.
8. Navigate to *Users\Public\Documents\Vicon\CalibrationObjects* and click **Select Folder**.
  The custom L-frame is automatically saved as a VSK.

**To use the custom L-frame:**


1. Click the Play button or **Exit Review** to resume the real time.
2. In the **Camera Calibration** panel, go to the **Volume Setup** section and ensure the advanced options are displayed > Macro (inline-media-image)

.
3. To the left of the wand list, ensure the Synchronize button is not selected > Macro (inline-media-image)

.
4. In the wand list, select the new custom L-frame.
5. Click **Set Origin**.
  The new custom L-frame is used to set the origin.
