Map Display 스크립트 만들기 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MapDisplay : MonoBehaviour {

	public Renderer textureRender;

	public void DrawNoiseMap(float[,] noiseMap) {
		int width = noiseMap.GetLength (0);
		int height = noiseMap.GetLength (1);

		Texture2D texture = new Texture2D (width, height);

		Color[] colourMap = new Color[width * height];
		for (int y = 0; y < height; y++) {
			for (int x = 0; x < width; x++) {
				colourMap [y * width + x] = Color.Lerp (Color.black, Color.white, noiseMap [x, y]);
			}
		}
		texture.SetPixels (colourMap);
		texture.Apply ();

		textureRender.sharedMaterial.mainTexture = texture;
		textureRender.transform.localScale = new Vector3 (width, 1, height);
	}
	
}

아까 만들어 둔 Map Generator에 Map Display Script 적용하기 

그러면 아래 사진처럼 2개의 스크립트가 적용되어 있는 것을 볼 수 있다.

GameObject > 3D Object > Plane

오른쪽에 Collider 창은 필요 없으니까 없애기
