first of all I am aware that we can multi-thread our gameplay, but does the engine/Editor itself uses Multi-threading? if yes can someone pinpoint me to where it is being used in the code

FRunnable FRHIThread FRenderingThread FAssetSearchManager FContentBrowserFileDataDiscovery FStreamSearch FAsyncSearchIndexTaskRunnable FRemoteBuildWorkerExecutor FRHIFrameOffsetThread And so on. There are more than a dozen threads in the engine.
