Hello,
I have an actor monologue system based on the DialogueVoice / DialogueWave infrastructure.
The system works until I display fullscreen UMG window. At that point caption is hidden beneath this window.
The sound always works, so only caption is invisible.
It’s the same as with DrawText so I presume it’s the common cause.
Is any fix planned or at least a workaround available?
Thank you!
Jan
Hello metamorphium,
I have a few questions for you that will help narrow down what issue it is that you are experiencing.
Quick questions:
Subtitles still displaying under umg widgets, and subtitles dont have any Z order option.
Tested in 4.17and 4.18 P4
Hello soulmapp,
Could you answer the questions that were asked of the original poster?
Create a clean project - Third Person Template
Create a umg widget, inside the umg widget, place a image widget, anchored to the bottom middle.
Create dialogue Voice and Wave, setup the dialogue with wav file and the subtitles you wish to display when the sound plays.
Level blueprint - Event begin play - add widget to viewport
And as you can see the subtitle text is behind the widget.
I was able to reproduce this issue on our end. I have written up a report and I have submitted it to the developers for further consideration. I have provided a link to the public tracker. Please feel free to use the link provided for future updates.

Make it a great day
Hello metamorphium,
We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.
Thank you.
I am also having a similar issue with the dialogue system not having any options for Z order or where the draw text is to be displayed on screen. Would appreciate any advice on how to code around this limited functionality in BP.
So after a lot of searching and not a whole lot of finding answers. I’ve discovered that there is nothing you can do about this in Blueprints, sorry folks. There is however, a solution if you want to dive into cpp, and its actually a really easy change to move the location the text shows up on the screen. The file you want is SubtitleManager.cpp and is located in your engines source code directory Engine/Source/Runtime/Engine/Private/SubtitleManager.cpp
One you have this open in visual studios you want to find the DisplaySubtitle function. This function uses the canvas to draw a text item which renders directly to the players display, so it is not compatible in any way with UMG and widgets, which is why changing the TextItem.Depth won’t have any effect on the draw order. Instead, the best you can hope for is to be able to move the location to somewhere you don’t have any active UI elements. I’m guessing there could be a way to program this function to implement a UMG solution and expose the z order and location properties to a blueprint you could then edit, but I didn’t have time to do that. Instead I had the function draw the code from the top down instead of the bottom up due to our game having a hot bar at the bottom. Below is the newly modified code (only a few small changes).
//For displaying subtitles to a good location
void FSubtitleManager::DisplaySubtitle(FCanvas* Canvas, FActiveSubtitle* Subtitle, FIntRect& Parms, const FLinearColor& Color)
{
if (OnSetSubtitleTextDelegate.IsBound())
{
// If we have subtitle displays, they should be rendered directly through those, not via the canvas.
DisplaySubtitle_ToDisplays(Subtitle);
return;
}
// These should be valid in here
check(GEngine);
check(Canvas);
check(Subtitle != nullptr);
CurrentSubtitleHeight = 0.0f;
// This can be NULL when there's an asset mixup (especially with localization)
if (!GEngine->GetSubtitleFont())
{
UE_LOG(LogSubtitle, Warning, TEXT("NULL GEngine->GetSubtitleFont() - subtitles not rendering!"));
return;
}
float FontHeight = GEngine->GetSubtitleFont()->GetMaxCharHeight();
float HeightTest = Canvas->GetRenderTarget()->GetSizeXY().Y;
int32 SubtitleHeight = FMath::TruncToInt((FontHeight * MULTILINE_SPACING_SCALING));
FIntRect BackgroundBoxOffset = DrawStringOutlineBoxOffset;
//SYMMETRIC - Set the minimum to be 1/5 of the maximum - jb
Parms.Min.Y += Parms.Max.Y/5;
// Needed to add a drop shadow and doing all 4 sides was the only way to make them look correct. If this shows up as a framerate hit we'll have to think of a different way of dealing with this.
if (Subtitle->bSingleLine)
{
const FText& SubtitleText = Subtitle->Subtitles[Subtitle->Index].Text;
if (!SubtitleText.IsEmpty())
{
// Display lines up from the bottom of the region
//SYMMETRIC - Changed to display lines down from the top of the region -jb
Parms.Min.Y += SUBTITLE_CHAR_HEIGHT;
FCanvasTextItem TextItem(FVector2D(Parms.Min.X + (Parms.Width() / 2), Parms.Min.Y), SubtitleText , GEngine->GetSubtitleFont(), Color);
{
TextItem.Depth = SUBTITLE_SCREEN_DEPTH_FOR_3D;
TextItem.bOutlined = true;
TextItem.bCentreX = true;
TextItem.OutlineColor = FLinearColor::Black;
}
Canvas->DrawItem(TextItem);
CurrentSubtitleHeight += SubtitleHeight;
}
}
else
{
for (int32 Idx = Subtitle->Subtitles.Num() - 1; Idx >= 0; Idx--)
{
const FText& SubtitleText = Subtitle->Subtitles[Idx].Text;
// Display lines up from the bottom of the region
//SYMMETRIC - Changed to dispay lines down from the top of the region -jbogaard
if (!SubtitleText.IsEmpty())
{
FCanvasTextItem TextItem(FVector2D(Parms.Min.X + (Parms.Width() / 2), Parms.Min.Y), SubtitleText, GEngine->GetSubtitleFont(), Color);
{
TextItem.Depth = SUBTITLE_SCREEN_DEPTH_FOR_3D;
TextItem.bOutlined = true;
TextItem.bCentreX = true;
TextItem.OutlineColor = FLinearColor::Black;
}
Canvas->DrawItem(TextItem);
Parms.Min.Y -= SubtitleHeight;
CurrentSubtitleHeight += SubtitleHeight;
// Don't overlap subsequent boxes...
BackgroundBoxOffset.Max.Y = BackgroundBoxOffset.Min.Y;
}
}
}
}Same problem at version 4.19
Really wish this was addressed.
Reported in 2016, still active in 2019…
Can you not simply expose or make use of the Z order flag by giving a Z order flag for all dialogue entries model / like it is
for the individual sound clips with Subtitle Priority?
Or, just make the subtitles always on top altogether like the C++ work around above part of the engine?
I don’t understand why this is not yet fixed in 2022. It is a real shame, I have the same problem, and I don’t like using my own engine build…
When is this going to be fixed?
