The scale of AAA games development is starting to reach obscene levels of craft. While our computers and consoles have become capable of rendering much larger environments, we've also become more demanding of the detail within those worlds.

Today we present a special episode of Cameron Robinson's science show Reality Check, where he visits Hello Games to uncover the tools and math that built an entire universe.
