Gravijta

Sorry if this is the wrong place to ask, but it seems to be the only place I can. I am interested in some of the UMA packs/characters, but require facial expressions and lip sync compatibility. Is this possible with the current version of these models? Also, are there still issues with downloading? I would love to have access to a sample to ensure compatibility with my project before committing to purchase. Any information would be greatly appreciated. Thanks!
