Looks beautiful, but didn’t they say they’re doing this in the same way as old games like Icewind Dale where they render out environments to layered 2D scenes?
The pre-rendered backgrounds is all part of the charm that brings us back to the Infinity Engine days of Baldur’s Gate, Icewind Dale, etc. While not impressive technically, they are still beautiful and provide lots of nice details in the environment for us to enjoy.
