Variables

  Type Name Description
Protected variable IAnimationStreamingManager * AnimationStreamingManager The animation streaming manager, should always exist
Protected variable IAudioStreamingManager * AudioStreamingManager The audio streaming manager, should always exist
Protected variable FCriticalSection AudioStreamingManagerCriticalSection Locks out any audio streaming manager call when we are re-initializing the audio streaming manager.
Protected variable int32 DisableResourceStreamingCount Count of how many nested DisableResourceStreaming's were called - will enable when this is 0
Protected variable float LoadMapTimeLimit Maximum number of seconds to block in StreamAllResources(), by default (.ini setting).
Protected variable Nanite::FCoarseMeshStreamingManager * NaniteCoarseMeshStreamingManager The nanite coarse mesh streaming manager, should always exist
Protected variable int32 NumIterations Number of iterations to perform. Gets reset to 1 each frame.
Protected variable FRenderAssetStreamingManager * RenderAssetStreamingManager The currently added texture streaming manager. Can be NULL
Protected variable TArray< IStreamingManager * > StreamingManagers Array of streaming managers to route function calls to
Protected variable FVirtualTextureChunkStreamingManager * VirtualTextureStreamingManager The virtual texture streaming manager, should always exist
