Texture Array Streaming

I’m interested in using texture arrays in UE4. I can get them to work fine, and generate mips, but I’m unsure if mips are actually streaming.

  • I’m pretty new to UE. Is there a way to debug view which mip is loaded?
  • Could someone please confirm whether mips for arrays are streaming?
  • If not, would virtual textures solve this issue as they don’t stream mips the traditional way.

Thank you for help!
