[ScriptedImporter(1, "cube")] public class CubeImporter : ScriptedImporter { public float m_Scale = 1;

public override void OnImportAsset(AssetImportContext ctx) { var cube = GameObject.CreatePrimitive(PrimitiveType.Cube); var position = JsonUtility.FromJson<Vector3>(File.ReadAllText(ctx.assetPath));

cube.transform.position = position; cube.transform.localScale = new Vector3(m_Scale, m_Scale, m_Scale);

// 'cube', being a GameObjects, will automatically be converted into a prefab. // (Only the 'Main Asset' is elligible to becoming a Prefab.) ctx.SetMainAsset("main obj", cube);

var material = new Material(Shader.Find("Standard")); material.color = Color.red;

// Assets need to provide a unique identifier string across imports with the assets changing, ctx.AddSubAsset("my Material", material);

// Assets that are not provided into the context as import outputs, // must be manually cleaned up var tempMesh = new Mesh(); DestroyImmediate(tempMesh); } }
