If a project that is set to Mobile/Tablet and Scalable 3D or 2D uses StartCameraFade() to produce a fade in effect, the effect will not play in PIE if the editor is closed/reopened.
1. Create new First Person code project
2. Set target to "Mobile/Tablet" and Graphical level to "Scalable 3D or 2D"
3. Create a new class based on GameMode (MyGameMode)
4. In MyGameMode.h add the following:
void BeginPlay() override;
5. In MyGameMode.cpp add the following:
void AMyGameMode::BeginPlay()
{
Super::BeginPlay();
APlayerController* pc = GEngine->GetFirstLocalPlayerController(GWorld);
if (!pc) {
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("NO PLAYER CONTROLLER!"));
}
APlayerCameraManager* cameraMan = pc->PlayerCameraManager;
if (!cameraMan) {
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("NO CAMERA MANAGER"));
}
float fromAlpha = 1.0;
float toAlpha = 0.0;
float duration = 2.0;
FLinearColor color = FLinearColor::Black;
bool bShouldFadeAudio = true;
bool bHoldWhenFinished = true;
cameraMan->StartCameraFade(fromAlpha, toAlpha, duration, color, bShouldFadeAudio, bHoldWhenFinished);
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("STARTED CAMERA FADE IN!"));
}
6. Compile the code
7. In the world settings inside the editor, set GameMode Override to MyGameMode
8. PIE - the screen will briefly be black and fade in
9. Save and close the editor
10. Reopen the editor and PIE
Result:
The fade in effect won't play after restarting the editor
Expected:
Fade in plays when targeting for mobile as well as "Maximum Quality"
