The Tools panel contains tools to quickly animate the model. Each tool is available only if the model creator enabled it (see Tools Options).

Lip Sync

Creates a viseme lip sync animation for the model mouth.

1. Choose the Input:
   • Text — English text, converted to phonemes with the CMU Pronouncing Dictionary.
   • ARPABET — ARPABET phonemes separated by spaces (e.g. HH AH L OW); stress digits are ignored.
   • Timed — a Text datablock with one label start end line per segment, in seconds. The label is a viseme or an ARPABET phoneme, e.g. from a forced aligner. Use it to sync the mouth to a recorded voice.
2. Adjust the settings:
   • Speed — speech speed (not used with Timed input).
   • Intensity — multiplier on the viseme peaks.
   • Smoothing — smoothing window in ms: higher values give a softer mouth, lower values crisper consonants (0 disables it).
   • Interpolation — Bezier or Linear keyframes.
   • New Action — replace the current Action with a new one, named after the text. Other keyframes in the current Action (e.g. Auto Blink) will not play anymore. If disabled, the viseme keyframes are replaced in the current Action.
3. Click Generate Lip Sync. The animation starts at the current frame.

Note

Timing is in seconds, so the animation does not depend on the frame rate of the scene.

Auto Breath

Animates a bone controlling the breath. Select one bone: its unlocked transformations are animated, with a rest value of 1 and a maximum value of 2. Frequency, amplitude and randomness of the breath can be adjusted.

Auto Blink

Animates the blink of the eyelids, using a random generator. The blink length and rate (blinks per minute) can be adjusted.

Lips Shrinkwrap

Shrinkwraps the lip bones to a selected Object (e.g. a glass or another character). An additional Object (or the same) can be used to add a friction effect on the lips. Click Apply to add the constraints, and the X button to remove them.
