CLOUD & PC

Heavy preparation,in the cloud.Streaming, on your PC.

We are preparing a system that moves heavy character preparation to the cloud to reduce the load on your PC. Cloud features are not yet publicly available.

Planned cloud preparation: Processing existing images and receiving results have passed limited trials. Public new-character creation is in preparation; connected uploads, requests and downloads will require internet access.
Display and stream on your PC: Character rendering, camera recognition, OBS and games run on your PC. This is not a service that continuously streams your rendered video from the cloud.

More: screen labels and differences from earlier versions

Limited trials verified cloud submission, GPU image processing, private storage, processing while the app was closed, and receipt after restarting it. Fully automatic creation of new characters and physical PC shutdown remain unverified. Public cloud creation is still being prepared.

Image generation and automatic transparency for arbitrary images are not available yet. Real-face tracking and simultaneous use with OBS need final testing.
