I’ve tried the Metahuman SDK extensively, including the Audio to Lip Sync feature. Yesterday, I was forced to purchase a subscription, with limited minutes. Yesterday I generated a Lip Sync fine, but today, when I try, it fails every time. I’ve now tried 5 times on a 5 minute audio, using up 25+ minutes of my limited time, with ZERO animations to show from the API. What do I do?
