Importing a model

Learn to import a .fbx model into the project and make a prefab.

Importing 3D Models (.fbx)

3D models created in external programs like Blender, Maya, or 3ds Max are typically exported to Unity in .fbx or .obj format. When dragged into the project's Assets folder, Unity automatically imports the model. Selecting the model displays geometry, rig, and material settings in the Inspector.

// Model file is placed inside the Assets folder:
// Assets/Models/Character.fbx

Creating Prefabs from Models

An imported 3D model can be dragged directly into the scene. However, to customize its components, attach scripts, and reuse it multiple times in the game, the scene object is dragged back into the Assets folder to become a Prefab. This allows all adjustments to propagate across instances from the template.

// Dragging the scene object into the Assets folder
// creates a reusable .prefab template object.

Exercise Model Loading Check

If the modelDosyasi variable satisfies the condition .EndsWith(".fbx"), print Debug.Log("Model yuklendi: " + modelDosyasi);.

Show example solution

using System;

public static class Debug
{
    public static void Log(object message) => Console.WriteLine(message);
}

public class Program
{
    public static void Main()
    {
        string modelDosyasi = "Hero.fbx";
        if (modelDosyasi.EndsWith(".fbx"))
        {
            Debug.Log("Model yuklendi: " + modelDosyasi);
        }
    }
}

Test yourself

Which file format is the industry standard most commonly preferred for importing models and animations into Unity?
- .mp3
- .txt
- .fbx
- .png
Show answer

.fbx — The .fbx format is the most widespread because it carries 3D geometry, bone structures, and animation data in a single file.

Model File Extension

string modelYolu = "Assets/Models/Karakter.____";
