I don’t know how it works in Unity but in UE4 you can’t read from the stencil buffer in a masked material, which means you have to use a translucent material. This makes it an expensive effect, and you’ll end up with the usual problems with translucent materials, namely you may get inconsistent lighting or sorting issues.

UE get player controller

  UGameplayStatics :: GetPlayerController ( GetWorld (), 0 );   Then you don't need to iterate through all of them. For example if you are in a Singleplayer Game. 더 ▼ 답변됨  Nov 13 '14 at 4:29 PM eXi 7.2k   ●   340   ●   195   ●   482 18 Depends on what you want to do and where you want to do it. The main way you'd do this is here. for ( FConstPlayerControllerIterator Iterator = GetWorld ()-> GetPlayerControllerIterator (); Iterator ; ++ Iterator ) { }   Some things have the owner variable as a  APlayerController  (`APlayerState`, etc) Clients only have 1 controller, their own. Servers have ALL controllers. You'll want to use  IsLocalPlayerController  to differentiate on the server. 더 ▼ 답변됨  Jul 02 '14 at 2:38 AM Crzyhomer  STAFF 1.3k   ●   35   ●   26   ●   104   dbrizov  Jul 02 '14 at 2:47 AM I see, thank you very much :)   Mungyun  Nov 13 '14 ...

 https://halisavakis.com/my-take-on-shaders-geometry-shaders/ My take on shaders: Parallax effect (Part II) By  Harry Alisavakis   on  Monday, March 11, 2019 Welcome to the second part of the tutorial on Parallax effects! Now, initially I intended for this tutorial to only have two parts, with which I so naively open on the  previous post . However, there’s probably going to be a third part on the series, the subject of which I won’t reveal now, for some dramatic tension. The subject of this part was what I initially intended to achieve and it led me to stumble upon the previous and next tutorials, for which I’m really grateful. It’s the effect that got me so excited about parallax, as I mentioned in the backstory of the previous post, and it’s the very same effect covered in that tutorial I mentioned before, but without the Shader Graph: 1 2 3 4 5 6 7 8 // Calculates UV offset for parallax bump mapping inline float2 ParallaxOffset( half h, half height, half3 vi...
