Harmony lets you control which deformers are displayed in the Camera view independently from the current selection. When you create a deformation chain, its deformation controls are displayed in the Camera view. However, if you select an existing deformer or a layer that's connected to existing deformers, its deformation controls won't display right away. Likewise, deselecting a deformation chain will not hide its deformation controls. Before you can animate or modify an existing deformation chain, you must manually display it.
In the Camera, Timeline or Node view, select one of the drawing elements linked to the deformation chain you want to display.
In the Timeline or Node view, select the deformation group or any part of the deformation chain you want to display.
In the Deformation toolbar, click the Show the Selected Deformation Chain and Hide All Others button.
The selected deformation controls appear in the Camera view and all the others are hidden.
NOTEThe Show the Selected Deformation Chain and Hide All Others button will display all deformation chains that are in the hierarchy of the selection. For example, if the master peg of a character model is selected, all of its deformation chains will be displayed. Likewise, if multiple layers linked with different deformation chains are selected, all of their deformation chains will be displayed.
