“While I’d love to give this a try myself, it’s only currently open to Google AI Ultra subscribers in the United States. Just in case you weren’t aware, that’s Google’s top-tier plan that costs $250/month. So, as you can imagine, access to this feature will be a bit limited for now.”
It does look pretty good from the video in the linked article. The thing though, with this type of functionality and realism, is you’re not going to be able to run this on your home server. It costs money to host services like these, so for the foreseeable future this will likely be a paid service of some sort (unless your virtual world can have lots of advertising billboards in it!).
But nice to see it is already technically possible.
