This is the second part of the tutorial series where I am going to implement a holographic 3D weapon printer for a game. When the system is finished, player will be able to go to the weapon printer and select the object needs to print and it will be printed through the system. Player will be able to pick it up and use it. Somewhat similar to the system in SubNautica game. In this part, we will implement the ability to select the weapon in the weapon printer using a UI and initiate printing. So, the selected model/weapon will be printed as a solid 3D object. We will create the UI widget and connect it with the existing printer. Ui will have buttons to cycle through available weapons.
