Looks nice!
I actually started building some portals myself just the other day for a puzzle game, and includes pretty much similar mechanics as to what you’ve shown.
I figured it might be a good discussion to start here as I don’t have a thread of my own yet, and I don’t think you have it your video either: how do you think a good way to get the portals scene capture 2d setup perfectly to display like your looking through a window? I personally tried doing some simple rotating of the scene capture based on the players location, but could never get good enough results.
