You can add custom prop meshes in Shogun Live and manipulate the prop during a shoot. These updates are seen instantaneously in engine, so that you can correctly position props and virtual cameras.

 Watch the Vicon video, [Shogun Live Prop Manipulation](https://youtu.be/o7X0QICz3H0) on YouTube.

> ℹ️ **Note**   
> ℹ️ As the videos were recorded using an earlier version of Shogun, you may notice minor differences in the user interface.

For information on using a custom L-frame to set the origin, see [Set the origin with a custom L-frame](https://vicon-help.atlassian.net/wiki/spaces/Shogun17/pages/13536854/Calibrate+cameras#CustomLFrame) in *Getting Started with Vicon Shogun*, Calibrate cameras.

For information on linking a calibrated SDI or Vicon Vue video reference cameras to a rigid tracking object, to enable the video camera to be tracked, see [Link a prop and a video camera](https://vicon-help.atlassian.net/wiki/spaces/Shogun17/pages/13537355).

**To create custom props:**

1. To make a custom prop mesh available in Shogun, copy the .*fbx* file into *C:\Users\Public\Documents\Vicon\PropMeshes*.  
(Any skinned FBX object can be a prop, provided the skin bone is called Root.)  
You can now select it from the **Mesh** drop down list as described below.
2. In Shogun Live, to make it easy to select the required trajectories, in a 3D Perspective pane, pause the real-time stream (press the space bar).
3. Select the markers in the correct order:
  1. Root
  2. Target
  3. Up vector
  4. Any other markers
4. In the **Tracking** tab, ensure the **Setup** tab is selected and in the **Prop** field, enter the name of the prop.
5. Click **Create**.
6. On the **Properties** tab, from the **Mesh** dropdown menu, select the .*fbx* that you made available in Step 1.
7. Un-pause the real time (press the space bar again) to see the prop and mesh move together.
8. To change the view of props independently of subjects, select **View Filters** and then select the **Props** options that you want at the bottom left of the pane.
9. To change the position of your new prop, pause the scene, select the root bone and use the Object Manipulator (select it at the top of the 3D Scene view or press M). Note that you can't currently use the manipulator in the Cameras view.
10. When you have finished manipulating the prop, its constraints are automatically updated and a new version is saved.
