Description

This class is mainly used to set up the character's facial and head controls. RIFaceComponent data include 12 facial bones, 60 facial morphs and 24 custom morphs. You can open the details panel in the Face Puppet interface and press Ctrl+F2 to display more detailed data. The numbered data in the front are the 60 morphs data, the next are 12 facial bones data, while the rest belong to the custom set. A few of the bones within the 12 facial bones have no effect. You can tell if it has no effect, therefore invalid, if the data name is marked "N/A". In addition, an expression clip needs to be set up in order to create expression keys.

Inheritance

RIBase > RIFaceComponent

Member Functions

AddClip ( self, kTime, strName, kLength )

Create a new expression clip.

kTime [IN] Clip start time - RTime
strName [IN] Clip name - string
kLength [IN] Clip length - RTime

Return

Success - RLPy.RStatus.Success
Failure - RLPy.RStatus.Failure
