There's no readme file in CTA3_Resources_for_Live_Facial_Mocap.zip
What is the user supposed to do with the .ctTBactor, .ctFBactor and .ctActor files in there?
Should the double-click them to open in the s/w after they've installed it? (they do seem to show a custom icon in 7-zip so probably they open directly, but a readme in the .zip file wouldn't harm)
All you need to do is unzip the file CTA3_Resources_for_Live_Facial_Mocap.zip, and then in CrazyTalk Animator 3 select File > Import Model and choose a character model from the unzipped folder. Alternatively once you have unzipped the files, just drag the models into CrazyTalk Animator 3.
Once you have one of the characters open in CTA3, just switch to Content Manager > Custom > Actor > Character and click the ADD (+) button at the bottom to save the character for later use.
