I just tested with Izzy "Face capture" free iOS oftware that streams data in osc. There free version is limited to 15 seconds. It records and exports data in fax and has plugin for unity. The only bad thing..... 75 Canadian dollars to unlock the full version. Too much.
It works superwell. Too expensive, but I wanted to let you know. I'll dig into more similar software.
@Woland Thank you very much for your work! I use the Google too because I don't speak very well in English, and even less I write, and I do not want to hurt the eyes of my readers with huge spelling errors. Thank you again, best wishes!
