Setpixels leads to a blank texture?

Questions & Answers

Hello!

I am trying to multiply two textures together and output the result on to a plane for testing purposes. The textures are read/write enabled. The issue is that although I receive no errors in the console the output texture is always blank. I have tried to just get the pixels from one of the input textures and then set them to the output without altering them in any way but I still end up with the same error.

Code posted below;

using UnityEngine;
using System.Collections;

public class TextureBlend : MonoBehaviour {

	public Texture2D noise1;
	public Texture2D noise2;
	public GameObject target_Object;

	Color[] _noise_Array1;
	Color[] _noise_Array2;
	Color[] _output_Array;

	Texture2D output_Texture;

	// Use this for initialization
	void Start () {

		output_Texture = new Texture2D (256, 256);

		_noise_Array1 = noise1.GetPixels();
		_noise_Array2 = noise2.GetPixels();

		for (int i = 0; i < (256*256); i++) {
			_noise_Array1 <em>*= _noise_Array2*;*</em>

* }*

* _output_Array = _noise_Array1;*

* output_Texture.SetPixels (_output_Array);
target_Object.renderer.material.mainTexture = output_Texture;*

* }*
}
Any ideas?

Remember to use Texture2D.Apply to actually apply the SetPixels changes.
