[edit] Description
This script lets you reverse normals. The normals will only be reversed in playmode so it will still look inverted when viewing in edit mode.
[edit] Usage
Attach the script to the mesh you want normals to be reversed
[edit] CSharp- ReverseNormals.cs
using UnityEngine; using System.Collections; [RequireComponent(typeof(MeshFilter))] public class ReverseNormals : MonoBehaviour { void Start () { MeshFilter filter = GetComponent(typeof (MeshFilter)) as MeshFilter; if (filter != null) { Mesh mesh = filter.mesh; Vector3[] normals = mesh.normals; for (int i=0;i<normals.Length;i++) normals[i] = -normals[i]; mesh.normals = normals; for (int m=0;m<mesh.subMeshCount;m++) { int[] triangles = mesh.GetTriangles(m); for (int i=0;i<triangles.Length;i+=3) { int temp = triangles[i + 0]; triangles[i + 0] = triangles[i + 1]; triangles[i + 1] = temp; } mesh.SetTriangles(triangles, m); } } } }
