A developer known as DeDelner has added a new mechanic to the upcoming recreation of Valve's Portal in Unreal Engine. This time, the developer has managed to create a seamless setup that allows the game's cubes to teleport. The artist commented that an Opacity Mask is used for the white walls to "make a hole in the wall". Behind these walls, there is a 3D box that renders the render target texture, but with reverse culling. "This avoids clipping for the player camera and for other actors as well. This allows seamless teleportation and consistent lighting", added DeDelner.
For those unaware, the developer has been working on an Unreal Engine-based Portal for more than a year now. DeDelner constantly adds new features from the original games and posts regular updates on Twitter. Here are some of the most recent posts:
