in 5.7 looks like Text3D imports all system fonts every startup- can we make that optional?

Hi Editor Friends!

void UText3DEditorFontSubsystem::OnAssetLoaded() calls LoadSystemFonts everytime we start the editor, which imports a bunch of fonts we don’t need or want people using. Any harm in turning this off? And do you see epic making this a config option in the future?

Thanks!

Hi [mention removed]​,

Sorry about the delay, I was just assigned this case. I will look into it and should get back to you soon.

Best regards,

Hi again [mention removed]​,

I was able to confirm the behavior you described. In UE 5.6 and 5.7, UText3DEditorFontSubsystem::LoadSystemFonts() is called during editor initialization and it enumerates and registers all system font families. On Windows, this results in 100+ system fonts being registered.

In UE 5.5 (when the plugin was still experimental), this behavior was more limited. However, in 5.6, 5.7, and a recent source build from UE5-Main (CL 50708264), the current behavior remains unchanged and all system fonts are loaded by default.

As a workaround, if you’re on a source build, you can make this optional by gating the call behind a config setting in UText3DProjectSettings:

// Text3DProjectSettings.h
 
	/** Load default system fonts on startup */
	UPROPERTY(Config, EditAnywhere, Category = "Text3D")
	bool bLoadSystemFonts = true;

// Text3DEditorFontSubsystem.cpp
 
void UText3DEditorFontSubsystem::OnAssetLoaded()
{
	bInitialized = true;
	LoadProjectFonts();
	
	if (UText3DProjectSettings* Text3DSettings = UText3DProjectSettings::GetMutable()) {
 
		if (Text3DSettings->GetLoadSystemFonts())
		{
			LoadSystemFonts();
		}
	}
}

With that guard in place, Text3D continued to function normally; system fonts were not loaded, and only the project fonts appeared in the picker (as expected).

Please let me know if this information works for you.

thanks Francisco! Luckily we’re on source so I just commented out the system font load completely- I just wanted to make sure it wouldn’t have unintended consequences. If this setting goes into a future engine version, we can make sure to turn it off nicely.

Thanks again!

Hi [mention removed]​,

Great to hear, that’s a valid approach for now. I’ll go ahead and close this case.

Best,

Francisco
