Ever since I first wrote about creating object outlines in Unreal Engine 4 I have wondered if it was possible to render them as soft outlines instead of harsh binary lines. A good example of soft outlines can be found in Valve's games like Left 4 Dead or CS:GO. There wasn't an easy way to blur the pixels at the time nor a decent way to down-sample the render target containing the outlined objects in order to make this blur operation cheaper. Overall it came to be too costly to come with a decent solution...

Survivor vision is an incredibly versatile and adjustable visual effect used to reveal more information, secrets and items to the player. It has many different applications and is incredibly easy to set up, customize and plug in to your project.
