Hi,
I have been using iClone Characters with Unity3D to make a realistic avatar for voice services such as Amazon Alexa.
I am making great progress as you can see in the 2 minute video below.

However, I am a little stuck now with extending my range of hand gestures. I have been using the motion packs from Reallusion but they are limited as I always need to start and end in the same position.
Any suggestions about the best way to build up a wider library of conversational hand gestures?
If you are experienced in this area or interested in working on this with me please reach out.
