I have iClone 7.5.3119.1 with the latest Live Face plug-in installed and I record facial motion with iPhone X. Following exactly the instructions at http://manual.reallusion.com/Motion_LIVE_Plugin/ENU/Content/iClone_7/Pro_7.0/29_Plug_in/Motion_Live/Synchronous_Audio_Recording.htm
audio is not recorded.
4. Activate the Record Audio for Viseme Track
checkbox. Select the audio input installed on your PC from the drop-down list
This audio input device works perfect with other applications for audio recording, skype etc.
After recording there is no Viseme, Voice, Lips track item available to select. The screenshot at point 3 of the online documentation of Motion Live was taken from a setup with Faceware Live. However, the audio recording should work the same way but it does not.
Your help is highly appreciated!
