Fully Functional Portals in Unity URP

Portal is one of the most celebrated videogames ever, and its core mechanic certainly got people talking when it first released. In this video, I go over some of the core concepts you'll need for making your own portals in Unity! This project uses quite a lot of C# scripting and a couple of HLSL shaders, but I try and go over the core bits in detail.

This project uses Unity 2019.4.12f1 and URP 7.3.1, but it should work with other versions, and it doesn't take many tweaks to work with the built-in render pipeline.
