Hi, I’m working on the settings menu of my game and I can’t find documentation or any info on how to change the brightness with a slider. I have also seen some games have a gamma option and I would like to add it too. Can anyone help?
Also someone told me to try this Auto Settings in Code Plugins - UE Marketplace but I don’t know how it works so… Yeah haha
Bind a slider widget to a float variable ( that variable could be in a lot of places, but possibilities are game instance, save game, blueprint, player etc ).
Have a post process in the level ( it could be placed, spawned or part of a BP ).
When the slider is moved, it changes the brightness value in the post process.
I can give you a code example if you want, but like I say, many different ways of doing it 
Hey! Sorry for the late late reply but yeah, an example could come in handy. Also, the gamma would work the same way right?
Put a post process volume in your level, set it to infinite extent.
Make a new widget BP. Put a slider in it. Down the bottom of the slider details, click the big green ‘on value changed’ button and put this code in:
Run the game. It actually works back to front, but you get the idea 
I can’t find the “get actor of class” node, only the “get all actors of class” node appears… Also: I don’t know how to set the post processing volume to infinite extent haha
Click on the PP volume, in the details panel:
Stop typing ‘getall…’, try typing ‘getactorof…’:
I can’t find the infinite extent thing, and I believe that is because we are working on different versions of the editor, since I’ve found the “unbound” option, which I think does the same thing?
And the same thing goes for the “Get Actor Of Class”, because it doesn’t appear, even if I uncheck the “context sensitive” box
I’m working on 4.17, which version are you on?
Sorry, unbound, that’s it.
For the actor thing, don’t pull off a pin, just click on the background and look for it.
Ok, then do this:
Getting there ( I don’t know how much you know / don’t ).
click on the post process node, in the details you have to tick the things you want to have on the node…
Can i see your ‘on value changed’ code now?
( Is that two sliders?.. )
It is only one! I don’t know whats going on either… Gimme a minute, I’ll post my code
Yeah, you connected it up wrong… :-/
Take a look at my piccy at the beginning…
Did you get there?..
