Adding a "3D image" in Unity typically refers to importing a 3D model. The primary and most straightforward way to bring a 3D model file into your Unity project is by dragging it directly into the Project window.
Importing 3D Models: The Basics
Unity is designed to easily integrate with various 3D creation software. Once you have a 3D model file saved from your preferred application (like Blender, Maya, 3ds Max, etc.), getting it into Unity is simple.
The Drag-and-Drop Method
According to the Unity documentation, the quickest way to import a 3D model is to drag a file into the project window.
Here's a simple breakdown of the process:
- Locate your 3D model file: Find the
.fbx,.obj,.blend,.max, etc., file on your computer's file system. - Open your Unity Project: Ensure the Unity Editor is open and your project is loaded.
- Drag the file: Click and drag the 3D model file from your computer's file explorer directly into the Project window within the Unity Editor.
Unity will then automatically begin the import process, bringing the model's geometry, materials (if included), and potentially animations into your project's Assets folder.
Post-Import Steps
Once the model is imported into your Project window, you can find it listed as an asset.
- Placement: To use the model in your scene, simply drag the asset from the Project window into the Hierarchy window or directly into the Scene view. This creates an instance of the model in your 3D world.
- Import Settings: When you select the imported model asset in the Project window, the Inspector window will display various import settings. As mentioned in the reference, the Inspector includes a "Model tab" where you can configure options related to scaling, mesh import, materials, animations, and more. Adjusting these settings is often necessary to ensure the model appears and behaves correctly in your scene.
Unity supports importing models from most popular 3D applications, making the transition from 3D modeling software to game development relatively smooth.
