Function Documentation

TrackRenderAssetEvent()

bool TrackRenderAssetEvent ( FStreamingRenderAsset *  StreamingRenderAsset, UStreamableRenderAsset *  RenderAsset, bool  bForceMipLevelsToBeResident, const FRenderAssetStreamingManager *  Manager  )

extern

Turn on ENABLE_RENDER_ASSET_TRACKING in ContentStreaming.cpp and setup GTrackedTextures to track specific textures/meshes through the streaming system.

Checks a texture/mesh and tracks it if its name contains any of the tracked render asset names (GTrackedRenderAssetNames).

Parameters

RenderAsset	Texture/mesh to check
bForceMipLEvelsToBeResident	Whether all mip-levels in the texture/mesh are forced to be resident
Manager	can be null
