V-Bones needs this to understand the difference between each sub-rig setup. You can still use other binding methods like Point binding and Layer binding, but you also need to use Selective Flexi-bind.

- Has a somewhat misleading *new* icon
- Opens/Collapses all group layers when no Vitruvian Layers exists
- Prevents manual drag/drop of layers or closing of group layers whilst it is selected

So if you are working with V.layers and leave Hide Vitruvian Layers selected, and move to another doc without V.Layers - it will prevent normal group/layer management - until Hide Vitruvian Layers is deselected. I got caught out with this and thought the app was going wacko.

For example, lets say you have a character that has normal jointed arms, but sometimes you want the character to have wavy noodle arms you want to animate with Sketch Bones. Vitruvian Bones will let you switch between the two different arm setups in the same character.

To do this, each sub-rig needs to share a common parent or root bone. In the case of these arms, they could both parented to the upper body bone or a shoulder bone. After you bind the artwork (i.e., using Use Selected Bones For Flexi-Binding or Layer Binding for each sub-rig and artwork), select the Vitruvian Bones tool, select all the bones you wish to include in the Vitruvian Bones Group (minus the parent bone,) and click Group. Now one sub-rig will remain visible while the others are hidden.

Notice that the first bone of the visible sub-rig has a special mark at the base...this is important. To switch between the sub-rigs, you select the bone with the special icon in its base, and then, in the Vitruvian Bones options, select the sub-rig you want to switch to from the Active Bone menu. Vitruvian Bones will hide the selected sub-rig, and reveal the selected sub-rig. Alternatively, you can cycle through the sub-rigs by pressing Alt-D or Alt-C.

There's more to using Vitruvian Bones, but that's the basics in a nutshell.

As mentioned earlier, you need to use Selective Flexi-bind or Layer Binding for Vitruvian bones to understand which artwork it needs to hide, and you can use Point Binding on top of this binding when you need to.
