Question by BreakerOfStems · Aug 14, 2020 at 10:17 AM · shader

How should I approach revealing just a glimpse of a room through a door using shaders?

Hi all,

First question ever, so please be kind.

I am trying to understand discarding vectors in Unity Shaders. I can 'cut' an object up using clip or with an if statement, but I don't quite have mastery over it. I'm trying to do the following;

alt text

The grey areas represent 100% transparent space, whereas the blue represents visible internals of the cube. From what I understand this may be possible with Shaders based on the direction the camera is facing, and I understand it may require a few Shaders to function correctly. I'm not interested in a how to, just some pointers on what my approach should be. I have searched for similar questions and concepts but from what I can tell there isn't much information on using clip to create specific shapes or external transparency. Using Shaders may be the wrong approach altogether. What ever information that could get me on the right track and stop me pulling out hair would be greatly appreciated!

Thank you! That is along the lines of what I'm after, I should be able to adapt it to my needs. I can't believe I didn't come across this!
