So I am trying to recreate the “looking glass” effect the game Prey has (Breaking Glass | Prey | Episode 1 - YouTube also very early game spoiler warning), but I cannot seem to get it right.
What I want to do is set up a scene outside the level and project that real-time onto a destructible mesh. I have tried using the “portal” effect using a render target and a plane but it’s not the same effect.
I have tried making a material of the render target, which makes a still image and thus doesn’t work. I’ve tried using a ScreenAlignedUV’s node with the material, but it moves with your perspective so that also doesn’t work. I also looked a bit into using a camera but I wasn’t able to get far.
I’m looking into this, but it’s my first time working with render targets and I’m not sure if it’s even the right thing to use. Could somebody help me?
