To create a picker for your rig follow these steps:

**1. Deform mesh with rig as you like.**

**2. Duplicate the mesh.**

**3. Duplicate head, scale it to the same size as body, move somewhere.**

**4. Create 512x512x1 cube, frame it and setrender resolution to 2000x2000 px.**
    You should get something like that:

**5. Hide the cube and render this image.**
    Background has to be transparent.

**6. Save image to your rig's project folder.**

**8. Place and sculpt created picker shapes as you like.**
    You can move, scale and rotate these curves, and pose your rig as you like(these shapes follow your rig).

    All that will be stored when you press "Export picker shapes" and can be imported back onto a updated
    rig by pressing "Import picker shapes" button.
