The Item Drop 3D component displays a 3D item in the game world. For the model to appear, "Require Model" must be enabled and an item with a 3D model must be set.
It's recommended to attach a trigger collider for interaction purposes. The default setup should already have this.
You can set an item with the "Set Item" button.
You have more control of this component through code! Visit the scripting section for more information.
