UNIVERSAL HUMAN

Additional Notes

Ground Collision

The Foot Main Control and Finger controls collide with the ground plane.  To allow them to pass through, disable their Floor constraints in the Bone Constraints panel.  To assign a specific object as a collision plane, select it under Target (currently set to Body).

Viewport Performance

The Face Rig, Body & Face Rig and Advanced Rig include two warp modifiers (Warp Eyelid L and R) which prevent the cornea from intersecting the eyelids.  Disabling them by toggling “Display Modifier in Viewport” can significantly increase real-time viewport performance.  This is also true of the Shrinkwrap and Smooth modifiers (also present on the Body Rig) which are used by the Musculoskeletal Systems.

Proportions

Corrective shapes can become distorted when using more extreme proportions.  They can be reshaped by selecting the applicable "Corrective" shape key and sculpting or editing it.

Controlling Shoulder Behaviour

If a shoulder joint pops or flips around, it's likely you've moved the arm into an unnatural position.  Try rotating the shoulder or upper arm, or repositioning the Arm Pole until it reorients itself.  If it deforms poorly in more extreme poses, try rotating the Arm Position proportion control to correct it.

Teeth

To change the position, scale or rotation of the teeth without affecting the lips or jaw as well, modify the teeth objects directly instead of using their proportion controls.

You can enable the "Baby Teeth" shape key for younger children (they usually last up to around age 6 or 7).  When using the Teeth & Tongue Rig independently of the other rigs, you'll also need to do the following:

1. Right click on the Body Age shape key's value.

2. Select Delete Driver - or if you want to keep the driver for later use, select Edit Driver and uncheck "Driver:".

3. Drag the value slider all the way to the right.

To swap out individual baby teeth for adult teeth:

1. With the Baby Teeth shape key selected, select a tooth in Edit mode (select a vertex at its tip and press Ctrl + on the numpad a few times)

2. Ctrl-V and Blend from Shape, select Basis in the panel that appears and uncheck Add.

The Teeth Upper and Teeth Lower controls automatically part to make room for adult teeth during the transition period, however further manual adjustments may be necessary to make them sit naturally.

Extracting Base Meshes from Advanced Rig

The race, gender and age base meshes are built into the Advanced Rig as shape keys.  If you want them to be separate static meshes, you can do the following (to create age base meshes, see note* below first):

1. Select the Basis shape key

2. Select all the Body vertices in Edit mode

3. Ctrl-V > Blend from Shape and select the required shape key. 

4. Exit Edit mode

5. In the Shape Keys Specials menu select Delete All Shape Keys

6. Select the Armature, enter Object mode and delete it

*Age base mesh: Move the Age control to the age you want, then in the Shape Key Specials menu select New Shape From Mix.  Then follow the 6 step procedure, selecting the newly created shape key at step 3.

To separate the head from the body, follow the first 20 seconds of the Race Head to Full-Body Rig Upgrade Procedure video, then delete the body.
