Run-time API for calculating mesh with smooth normals can be brought into scope with this using directive
using AmazingAssets.Beast;
Unity class now will have GenerateSmoothNormals extension method:
// Generating mesh with smooth normals
using UnityEngine;
using AmazingAssets.Beast;
public class NewMonoBehaviourScript : MonoBehaviour
{
public Mesh mesh;
public Mesh meshWithSmoothNormals;
private void Start()
{
meshWithSmoothNormals = mesh.GenerateSmoothNormals();
}
}
