About LOD Stream Settings

  • Project Settings: Mesh Streaming
  • Static Mesh Settings: Num Streamed LODs, NoRef Streaming LODs

I want to reduce the memory consumption of LODs by LOD Streams, like only load LOD3 by default, load LOD2, 1, 0 when necessary. What should I do? Are the above settings helpful? I just read the description of them but not understand exactly.
