Array is Not Returning It's Entire Length

I'm trying to get an array of all of the materials on a gameObject when the scene starts. I have a function called GetOriginalMaterial() that will find the Renderer component in each of the children gameobjects and get the materials. For each of the materials found, they will be stored in a variable called originalMaterials for later use.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class EnemyControllerCopy : MonoBehaviour
6. {
7.  
8.     //variable for the Renderer array
9.     [SerializeField]
10.     private Renderer[] skinMeshChildren;
11.     //variable for the original materials
12.     [SerializeField]
13.     private Material[] originalMaterials;
14.  
15.  
16.     // Start is called before the first frame update
17.     void Start()
18.     {
19.      
20.         //get the renderer components of this gameobject's children
21.         skinMeshChildren = GetComponentsInChildren<Renderer>();
22.         //upon starting the scene, get the game object's materials that it started with
23.         GetOriginalMaterial();
24.     }
25.  
26.     // Update is called once per frame
27.     void Update()
28.     {
29.      
30.     }
31.  
32.     private void GetOriginalMaterial()
33.     {
34.         //for each of the Renderer components in the children
35.         foreach (Renderer rend in skinMeshChildren)
36.         {  
37.             //get the total number of materials that is in the Skinned Mesh Renderer in the children
38.             //any material found in the children is going to be the original material that the gameobject started with
39.             for (int i = 0; i < rend.materials.Length; i++)
40.             {
41.                 originalMaterials = rend.materials;
42.             }
43.  
44.         }
45.     }
46. }
47.  

When I start the scene however, I don't get all of the materials from the child game objects, and that is the current problem that I am trying to solve.


Here we see that there are 3 materials on this game object called Body_Material, Body_Plastic and Body_vinyl.


However when the scene starts, the script is only able to grab 2 materials. What happend to Body_vinyl?

 

Code (CSharp):

1. originalMaterials = rend.materials;

You're just overwriting your materials array each time.
Try using a List<> and doing AddRange
