Fake crystal using render textures
Hello.
For some time I have been looking for a way to achieve something similar than the "Fake crystal" thing that can be found in Prey.
You can notice this effect in the following video around the minute 15:45 (SPOILER ALERT)
I have tested a few things but can not achieve the same effect. I have a render texture acting as a window and a camera in other room, but I find so difficult to get the sensation of depth when moving and looking around. I am probably failing with the maths when moving the camera with the character in an attempt of making this work.
Please forgive my english, English is not my first language.
I am not very familiar with Unity's rendering setup, so I can't give you exact instructions, but here is the way I would do it:
Let's assume that you have a glass wall with a hole in it. Scene A is the nice appartment + nice view. Scene B is all the stuff behind the hole (machinery and stuff.
You need only 1 camera for this, which is your main view camera and you don't really need render targets. Here are the steps:
Render Scene A
Render the glass wall into the stencil buffer, so that only what is in the hole gets drawn
Render Scene B using the stencil buffer
As I said, I don't know the exact steps to do it with Unity, but I think it should be relatively easy to replicate.
