In Shogun Live, you can create simple, single-segment (and therefore rigid) props.
For information on working with props, see:
For information on creating a prop as a custom L-frame, see Set the origin with a custom L-frame.
Place markers on props
When placing markers on props, note that minimum of four markers is recommended for each prop. 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 will interact 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:
To create a single-segment prop:
- Ensure the markers are positioned on the prop as described above.
- Place the prop in the volume.
- In Shogun Live, in the Settings menu, click Show Preferences (or press SHIFT+P).
- In the Preferences dialog box, on the Folders for username tab, ensure that the Props folder is as required, or if not, click Browse to specify the appropriate folder.
- In the 3D Scene, select a minimum of four reconstructed markers. 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.
- On the Subject Calibration tab, in the Props section, enter a name for the prop and click Create Prop. (Note that, if required, you can also select a mesh for the prop from the selection in the Mesh field. Prop meshes are FBX files, by default stored in C:\Users\Public\Documents\Vicon\PropMeshes).
A single-segment prop is created from the selected markers and appears in the 3D Scene in the orientation defined by the order in which you selected the markers in the previous step.
The prop is displayed as a node on the Subject tab on the left of the Shogun Live window, under Props.
The prop's .mcp file is saved to the location specified in step 2 above.
- To save or remove a prop from the current scene, on the Subject tab, right-click the prop and then click the relevant option.
After you have saved props, you can import them into subsequent takes as required.
Note that in addition to creating simple, single-segment props, you can also import both simple props and more complex, multi-segment props by clicking the Import Props button at the top of the Subject panel:
To move props in Shogun Live, you use the Object Manipulator, at the top of the 3D Scene view.
To use the Object Manipulator:
- Select the object and if the Object Manipulator isn't displayed, click the Object Manipulator button or press M.
- Drag to move the prop in the 3D Scene view or enter the required values in the Object Manipulator fields.
- To change between global and local values, click the Object Manipulator symbol:
You can use the manipulator to quickly align a prop to the world axis.
To align a prop to the world axis:
- Pause the real time and in the Subject pane on the left, select the prop you want to align and press M to display the Object Manipulator.
In the Workspace (3D Scene view), the Object Manipulator is displayed. By clicking on the Object Manipulator symbol (top left), you can set it to Local (values at zero) or Global (values relative to the scene origin).
- To align the selected prop to the scene origin, ensure the Object Manipulator is set Global and change all the values to zero.
