Merging two different texture into one in unity3d

Questions & Answers
1

i am trying to merge two textures into one in unity
the first texture is from a webcamTexture
the second is from a sprite using : gameobject.getComponent().sprite.texture as Texture2D

I’m having problem in writing the function this is what i did so far :

public static Texture2D CombineTextures(GameObject obj, Texture2D background, Texture2D TodrawLogo)
{
	Vector3 v = obj.transform.position;// obj is TodrawLogo gameobject
	int width = TodrawLogo.width;
	int height = TodrawLogo.height;
	for (int x =(int)v.x; x < width; x++){
		background.SetPixel(x,(int)v.y,TodrawLogo.GetPixel(x,(int)v.y));
	}
	background.Apply();
	return background;
}

this what i am trying to do :

WebcamTexture

the result Texture should be like this
41366-nnuts.png

The webcamTexture is a 3d Plane and the logo is a single sprite

but sadly my function doesn’t work
does anyone know how to fix this
I know that i should find the exact coordinate of the todraw image and set the pixels but i can’t figure out how

Much appreciation

I don’t know about the opening of the cupboard door behind but for the logo, you could actually add it at runtime.

IEnumerator TakeScreenshot(){
    logo.SetActive(true);
    yield return new WaitForEndOfFrame();
    var tex = new Texture2D( Screen.width, Screen.height, TextureFormat.RGB24, false );
    tex.ReadPixels( new Rect( 0, 0, Screen.width, Screen.height ), 0, 0 );
    tex.Apply();
    logo.SetActive(false);
}
