I hope it's ok to necro this thread. :poly136: Was this released yet? I would really like to see it in action, but I can't find new information related to Quixels megascan. On their site - http://quixel.se/megascans/ - is sadly nothing new.
Here's a picture of the scanner itself. They had an iPad to show off some more about MegaScans, as well as the flythrough video of an environment and the site itself.
