In the UE5.8 release note they mentioned this:

Fixed an issue with Skeletal Mesh streaming where streamed LODs remained in memory until the Skeletal Mesh was destroyed.

Anyone knows where in the code base is this fix? The change could benefit my project so I appreciate any helps. Many thanks!

Hi there,
This fix only affects Skeletal Meshes generated at runtime by the Mutable Plugin. Are you using the plugin to generate the Skeletal Meshes?
If that’s not the case and Skeletal Meshes memory is high, you could set ‘r.FreeSkeletalMeshBuffers’ to 1. This will free the CPU side memory after uploading the SKM buffer data to the GPU.
