Description

ProjectWorldToScreen always returns true.

User states:

"This probably comes from that line of code :
bResult = Player->PostProcessWorldToScreen(WorldPosition, ScreenPosition, bPlayerViewportRelative);

(In the definition of ProjectWorldToScreen in UnrealEngine/Engine/Source/Runtime/Engine/Private/GameplayStatics.cpp)

Because that function is defined that way :

bool APlayerController::PostProcessWorldToScreen(FVector WorldLocation, FVector2D& ScreenLocation, bool bPlayerViewportRelative) const

{ return true; }

(In UnrealEngine/Engine/Source/Runtime/Engine/Private/PlayerController.cpp)"

Steps to Reproduce

1. Use ProjectWorldToScreen node in a 4.19 project (Image of my setup attached)
2. PIE and look around (0,0,0 location will be projected to x,y of screen)
3. When looking away from 0,0,0 "true" will still be output (Would change to false in 4.18)
