Blendshapes

Estimated reading: 21 minutes

Wonder Studio supports facial animation by utilizing blendshapes based on FACS (Facial Action Coding System).
Our system supports 88 unique blendshapes. The animation will be generated by analyzing your video and then applying the resulting animation to the character’s blendShapes.

Blendshapes will need to be named correctly in order for the system to recognize them.

Although not mandatory, it is highly beneficial to have a full set of blendshapes.The system will use the available blendshapes.
The fidelity of the animation will increase if more shapes are available.

The following part of the documentation will focus on providing names and descriptions for all blendshapes and demonstrating their function.
Blendshapes are split into several groups that represent parts of the face those blendshapes are activating.
For each group of blendshapes, there can be up to 3 (three) tiers. Tiers should provide a clear progression from basic (First Tier) to intermediate (Second Tier) to full functionality (Third Tier). Note that tiers do not indicate the difficulty of creating a certain blendshape.

Gaze

Eye rotations, in the examples below, are for illustrative purposes only and should not be a part of this shape. For more information on how to set up eye bones for Wonder Studio visit the Linking Eyes page.

eyeDn

“eyeDn”, “eyeL”, “eyeR” and “eyeUp” are all meant to work together to change the shape of the eyelid as the eyeball rotates.

eyeL

“eyeDn”, “eyeL”, “eyeR” and “eyeUp” are all meant to work together to change the shape of the eyelid as the eyeball rotates.

eyeR

“eyeDn”, “eyeL”, “eyeR” and “eyeUp” are all meant to work together to change the shape of the eyelid as the eyeball rotates.

eyeSquintL

“eyeSquintL” is a squint shape for the lower lid. Tip: it is good to move the line beneath the lower lid on this shape. Moving that line keeps the face alive and aids in keeping the eye looking "happy" during smiles.
