Create props

This page covers how to create a single-segment prop. These are also known as rigid props. To create a prop in Shogun, you first need to place the markers on the physical prop so it can be captured in the software.

Place markers on props

When placing markers on props, note that a minimum of four markers is required for each prop. During marker placement, be sure to:

• Place the markers across the prop object to reach the extremities as far as possible.

• Avoid placing markers in a straight line and/or on the same plane.

• Avoid placing markers symmetrically.

• Prevent marker swaps by avoiding placing prop markers too close to the hands or where the actor will interact with the prop. For example, if a performer interacts with a prop, place markers at the extremities of the prop, but not directly in the location where the interaction occurs, as shown below, where a performer holds a sword:

After you have placed the markers on your prop, you can now create a single-segment prop in Shogun.

Create a single-segment prop:

1. Ensure the four markers are positioned on the prop as described previously.

2. Place the prop in the volume.

3. In Shogun Live, in the Settings menu, select Preferences (or press SHIFT+P).

4. In the Preferences dialog box, in the User Preferences, go to the Folders section and ensure that the Props folder is as required. If the Props folder is not set up or in the right location, click the button to the right of the Props line to specify the appropriate folder.

   Open

   

5. In the 3D View, select the minimum four reconstructed markers for the prop.
   To ensure that Shogun Live places the bone logically within the prop, select (CTRL+click) the markers in the following order:

   • The first selected marker defines the origin (base) of the prop bone.

   • The second selected marker defines the end of the prop bone.

   • Any other markers can be selected in any order.

     Open

     

6. In the Tracking panel, click the Setup tab.

7. In the Object section, go to the Prop field, enter a name for the prop and click Create.

   Open

   

   A single-segment prop is created from the selected markers and appears in the 3D View in the orientation defined by the order in which you selected the markers in step 5.

   The prop is displayed as a node in the Tracking panel on the right of the Shogun Live window.

   Open

   

   The prop's .mcp file is saved to the location specified in step 4 above.

8. If required, to select a mesh for the prop, or to change its color, in the Tracking panel, ensure that the prop is selected, and on the Properties tab below, choose a mesh and/or color. Prop meshes are FBX files, by default stored in: C:\Users\Public\Documents\Vicon\PropMeshes

You have now created a single-segment prop.
