Hello,

Instead of stripping the Nanite Fallback at runtime, you can strip them at cook-time.

These two CLs from //UE5/Main implement a method of stripping the Nanite Fallback during cook.

  • CL 40280437 - Primary Implementation
  • CL 40871224 - Fix for an edge case with ISMs

The description for CL 40280437 has information about the usage for Nanite Fallback meshes, and how the decision to strip them is made.

Please let us know if this helps.
