Description

UNiagaraDataInterfaceSkeletalMesh::CopyToInternal and UNiagaraDataInterfaceSkeletalMesh::Equals do not account for the component tags, so the tags array will be empty when the DI is copied.

Steps to Reproduce
  1. Create a new Niagara system based on the fountain template
  2. Add a skeletal mesh location system to it
  3. Add an entry to the Component Tags array with a value of "Test"
  4. Save the system
  5. Add the system to a skeletal mesh in the level

RESULT

The system will still sample the mesh even though it does not have the tag "Test" adding another mesh with the correct tag will not cause it to be sampled

 

NOTE: Restarting the editor will clear the mesh tags
