Visualize mesh normals in Unity3D

Visualize the normals of a mesh

It's meant to be simple and easy to use, and therefore it has been made as a custom editor of MeshFilter. It needs no preparations.

How to use

Drop the file in an Editor folder.

using UnityEditor;
using UnityEngine;
public class NormalsVisualizer : Editor {
private Mesh mesh;
void OnEnable() {
MeshFilter mf = target as MeshFilter;
if (mf != null) {
mesh = mf.sharedMesh;
void OnSceneGUI() {
if (mesh == null) {
for (int i = 0; i < mesh.vertexCount; i++) {
Handles.matrix = (target as MeshFilter).transform.localToWorldMatrix;
Handles.color = Color.yellow;
mesh.vertices[i] + mesh.normals[i]);
