1. 官网异步加载文档

https://docs.unrealengine.com/zh-CN/Programming/Assets/AsyncLoading/index.html

2. 官网中的UGameGlobals，没有找到。

3. 解决方法：参考Engine\Source\Runtime\UMG\Private\Components\Image.cpp

void UImage::SetBrushFromSoftTexture(TSoftObjectPtr<UTexture2D> SoftTexture, bool bMatchSize)
{
	CancelTextureStreaming();

	TWeakObjectPtr<UImage> WeakThis(this); // using weak ptr in case 'this' has gone out of scope by the time this lambda is called

	StreamingHandle =
		UAssetManager::GetStreamableManager().RequestAsyncLoad(SoftTexture.ToSoftObjectPath(),
			[WeakThis, SoftTexture, bMatchSize]() {
				if (WeakThis.IsValid())
				{
					WeakThis->SetBrushFromTexture(SoftTexture.Get(), bMatchSize);
				}
			}, FStreamableManager::AsyncLoadHighPriority);
}
