Update Reflection Capture on Runtime

[bayanm9]

@TobiGroth

So, I have build something…

Pros

• It updates the reflection captures

Cons

• It does **NOT **work in the packaged game! (because of this check in ReflectEnvironmentCapture.cpp (line 1439))

if (FPlatformProperties::RequiresCookedData())
{
UE_LOG(LogEngine, Warning, TEXT("No built data for %s, skipping generation in cooked build."), *CaptureComponent->GetPathName());
return;
}

• It’s hacky
• short hickup (which was to be expected)

for (ULevel* Level : World->GetLevels())
{
if (Level->bIsVisible)
{
if (Level->MapBuildData)
{
Level->MapBuildData->InvalidateReflectionCaptures(nullptr);
}
}
}

FScene* Scene = (FScene*) World->Scene;
if (Scene)
{
TArray<UReflectionCaptureComponent*> ReflectionCapturesToUpdate;
for (TObjectIterator<UReflectionCaptureComponent> Itr; Itr; ++Itr)
{
if (IsValid(*Itr))
{
ReflectionCapturesToUpdate.Add(*Itr);
}
}

bool bOldIsEditorScene = Scene->bIsEditorScene;
Scene->bIsEditorScene = true;
World->Scene->AllocateReflectionCaptures(ReflectionCapturesToUpdate, TEXT("UpdateReflectionRuntime"), false);
Scene->bIsEditorScene = bOldIsEditorScene;
}
else
{
// IT DIDN'T WORK
}

Using UE4.21 btw

If anyone can figure out how to get it to work in the packaged game without editing engine source code I’d be very grateful!

Can you please share where do you enter this code?
are you replacing the code after line 1439?
