Good question! Yes, it's an ongoing project, which over the last couple of years has been focussed on a Unity plugin version of Apparance. This has been developed in conjunction with two teams that are licensing the technology for their games, one is in early access (Gloomhaven Digital), the other is an unannounced title. Unfortunately, working solo, I haven't had the resources to get a public version of the Unity plugin released yet (requires a lot of polish, support, documentation, etc). In the new year however, I will be starting on the Unreal plugin version (having received an Epic Megagrant) and this will also bring the release of the Unity version closer. Follow myself and Apparance on Twitter for updates and information.
Thanks for asking.
