how to properly set a texture?
my question is how to set the noiseMap texture thats made in mapDisplay to the gameobj i transform into a plane/map in meshbuilder as you can see i have commented lines that i have tried but everything i have done has failed. for what ever reason the noise will not appear. i even tried getting rid of mapDisplay and mapgenerator completely adding everything to meshbuilder and calling it in gamefunctionality but that also did not work. does anyone know what mistake i'm making? just to be clear mapDisplay,noise, and mapgenerator are scripts i made using a tutorial
script one mapDisplay
using UnityEngine;
using System.Collections;
public class mapDisplay : MonoBehaviour
{ //public Renderer textureRender;
//public static Color[] colorMap;
//public Texture2D texture;
public void drawNoiseMap(float[,] noiseMap)
{ int width = noiseMap.GetLength (0);
int height = noiseMap.GetLength (1);
Texture2D texture = new Texture2D (width,height);
Color[] colorMap = new Color[width * height];
for (int y = 0; y < height; y++)
{ for (int x = 0; x < width; x++)
{colorMap [y * width + x] = Color.Lerp (Color.black, Color.white, noiseMap [x, y]);
}
Debug.Log("yes made it" + colorMap);
}
texture.SetPixels (colorMap);
texture.Apply ();
gameObject.GetComponent<MeshRenderer>().sharedMaterial.mainTexture = texture;
gameObject.transform.localScale = new Vector3 (width, 1, height);
}
}

Are you trying to use the legacy materials or the new ones?, because there's a difference between those types.
not sure about that im new still. im trying to get the texture2d that is made in mapDisplay and apply it the the plane made in meshbuilder from pressing the button thats in gamefunctionality. so far my attemps have failed to being just white. no texture at all or just red. which is why i set it to blue atm.
void mapGen() was orignally
void mapGen(){
mapGenerator mapBuild = GetComponent<mapGenerator> () as mapGenerator;
mapGenerator.generate$$anonymous$$ap();
}
line 21 of map display is it that im getting the compent the problem would it work if i just did
gameObject.GetComponent<$$anonymous$$eshRenderer>().shared$$anonymous$$aterial.mainTexture = texture;
to
gameObject.$$anonymous$$eshRenderer.shared$$anonymous$$aterial.mainTexture = texture;
in map display i uncommented the public renderer and changed lines 21-22 to use the public renderer ins$$anonymous$$d of gameobj still doesnt show the noise...
Sorry, but I don't understand what do you really want, and here is where I said - "To get the right answer you need the right question" -.
