Hey devs!
As I wasn’t able to find any decent answer I need an advice from one of you - materials masters 
I am working on a cool VR project with Hi-Tech tools and one of them is supposed to be a shield, but not just shield! Depending on some circumstances it can become to be either blocking or reflecting shield or a hiding shield to hide the Player behind it.
This should work as a cover f.ex. if you are trying to flee from an enemy Player you can use that shield and it will make the Actor (and it’s all children) invisible (fully or partially, doesn’t matter) for the players that stand on the other side but the environment should not be affected by this effect
There are plenty tutorials for a Highlighted object with the X-ray effect but what I need is kinda reverse and I really couldn’t find my answer
How would you go about such Material or maybe you know a nice source where it already exists?
Thanks in advance mates and wish you an amazing day!
