I wrapped up all the different portal tests I did so far into one plugin and project:
You can get the whole project here:
It’s a collection of my tests, tidied up, but not very much documented. Since a lot of people have asked me many times to do it: Here it is! I released it under MIT license so you can do with it what you want. There will be no dedicated support, though.
I want to give thanks to:
AgentMilkshake1 for laying the groundwork in getting a screen space projection for VR.
Andrew Hurley for explaining how to get a left/right vr mask into a material
