Deep copy a Mesh in Unity 2020+

MeshUtil.cs

using UnityEngine;

public class MeshUtil
{
    public static Mesh DeepCopy(Mesh sourceMesh)
    {
        //Instead of getting all a mesh's properties by hand, and re-creating a mesh,
        //use the API used for the job system and Burst compiler. 
        //This seems to work fine when not using either of those. 
        Mesh meshCopy = new Mesh();
        var meshData = Mesh.AcquireReadOnlyMeshData(sourceMesh);
        Mesh.ApplyAndDisposeWritableMeshData(meshData, meshCopy); //Takes care of the disposing as well
        
        return meshCopy;
    }
