Base Mesh Upgrade Procedure

Use this procedure to append the Female, Male or Child Base Mesh to the Body Rig/Body & Face Rig, or the Head Base Meshes to the Face Rig. For age morphing, select the "Age" blend file, not the "Child" variant when appending.

Important: Ensure you've downloaded the current versions before proceeding.

Child to Adult Base Mesh Morphing Procedure

Use this procedure for creating a linear transition from the Child Base Mesh to the Male or Female Base Mesh, or the Child Head Base Mesh to any of the Head Base Meshes. Note that this is less accurate than using one of the rigs, as it doesn't account for proportional changes throughout the "growth".

Important: Ensure you've downloaded the current versions before proceeding

Child to Adult Base Mesh Morphing Procedure.mp4

Load the Male or Female Base Mesh or Head Base Mesh
Apply the Armature modifier
Append the Child Base Mesh (or Head Base Mesh) (select Child, not Age), and in the Objects folder select Body, Eye L and Eye R
Shift-select original mesh and add a shape key
In the Shape Keys Specials menu, select Join as Shapes.
Delete the Child mesh (Body.001)
Go to frame 25 in the Timeline and keyframe the Body.001 shape key
Keyframe the adult eyeballs (Eye L and Eye R)
Move to frame 4
Set the Body.001 shape key value to 1.0 and keyframe it
Select the Child eyeballs (Eye L.001 and Eye R.001) and copy their Location, Rotation and Scale values to Eye L and Eye R
Keyframe Eye L and Eye R, and delete Eye L.001 and Eye R.001
Now you can scrub through the keyframes to get a linear morph, with eyes remaining in place.

Teeth & Tongue to Body Rig Upgrade Procedure
