I’m trying to do a line of sight that is fading from the border and I want the “unknown” to be like 25 to 35% dark not pitch black.
Right now I have this:
Here’s my workflow:
Event Graph from Character:
I’m brand new in blueprints so you’ll need to talk to me like i’m 5 !
I used this tutorial:
Hope you can help !
I’d do it with a post process, actually ( more efficient also ).
Just had ( and watched ) a million line conversation about something very similar to this
( we get there in the end… )
Okay so not with Line Trace By Channel ?
Not for the effect you’re going for… 
Ooohh I see, so it’s only in the material ?
And I guess it will be less heavy then tracing lines from the player ?
I tried with only the material, but how can I update the shape so it’s like what I had before with the line trace ?
Apologies, I didn’t look at your original pic for long enough.
I don’t think you’ll be able to get that effect with the pillars.
But this is much cheaper
And what do I need to change to reveal the pitch black part ?
I’ve tried to change the “A” in the Lerp but I don’t know what to do 
It’s these two params
Hardness actually only goes from 0 to 1, I don’t know why all the examples set it on 50 or 500
