Inventory screen and the Wardrobe Camera

Camera Culling
The camera layer by default is set Ignore Raycast and Targetable, it will cull anything else from the display. If your character is not set to this, then the camera will not display the character on the Inventory Screen.
Character Layer
Here you can see that the player is set to the targetable layer and the character is displaying in the inventory screen.
Wardrobe Prefab
The prefab for the Wardrobe is located at Assets/Dragonsan/Prefabs/Wardrobe.prefab loading this into the Prefab Manager will allow you to adjust the location of the character that is spawned.
You can see the default position of the character capsule, which is where the player will appear. While in play mode adjust the camera where you want it to be, and then copy this and paste it into the wardrobe prefab transform above to make the changes permanent.
