Plain public list not showing up in Inspector

I have 2 public lists that will just not show up in the inspector. Other variables, such as int and string, show up just fine.

Code (CSharp):

1. public class PlayerInfo : MonoBehaviour {
2.     [SerializeField]public List<Item> inventory = new List<Item>();
3.  
4.     [SerializeField] List<Skill> skills = new List<Skill>() {
5.         new PlayerSkills.Alchemy(),
6.         new PlayerSkills.Crafting(),
7.         new PlayerSkills.Herbalism(),
8.         new PlayerSkills.Magic(),
9.         new PlayerSkills.Mining(),
10.         new PlayerSkills.Smithing(),
11.         new PlayerSkills.Strength(),
12.         new PlayerSkills.Summoning(),
13.         new PlayerSkills.WoodCrafting(),
14.         new PlayerSkills.Woodcutting()
15.     };
16.  
17.     void Start () {
18.     }
19.    
20.     // Update is called once per frame
21.     void Update () {
22.        
23.     }
24. }

 

Do you have Item and Skill marked as Serializable? As in, the classes need [Serializable] on them. Also, your skills list isn't public.
