Issue changing duplicated object texture

Question

I have an object w$$anonymous$$ch has a mainTexture with a shader value of "Legacy Shaders/Transparent/Cutout/Diffuse". Upon Startup, I set the initial mainTexture and the cutout transparency works great.

Example:

       t$$anonymous$$s.GetComponent<Renderer>().material.mainTexture = Resources.Load("Images/ImageOne") as Texture2D;

Next, I am creating several duplicates of the original object and as long as I don't change the mainTexture, the cutout transparency sticks, but if I update the mainTexture by loading in a new png image similar to the way I did the initial image, the cutout transparency is removed.

Example:

         GameObject newObject;

         newObject = Instantiate(t$$anonymous$$s.gameObject, new Vector3(t$$anonymous$$s.transform.position.x,
                                                         t$$anonymous$$s.transform.position.y,
                                                         t$$anonymous$$s.transform.position.z  + Offset), Quaternion.identity);

          newObject.GetComponent<Renderer>().material.mainTexture = Resources.Load("Image/ImageTwo") as Texture2D;

I have tried copying over the original objects shader following the update to the image without success as well as various other t$$anonymous$$ngs.

Does anyone know how I can make the original shader implementation stay put after loading the new image or a way to update it back to the original objects shader so the transparency cutout will work?

I found the issue with t$$anonymous$$s. Unity docs describe how to do what I wanted to do (https://docs.unity3d.com/ScriptReference/Object.Instantiate.html) and so I was using the example to guide me in my implementation.

As it turns out, each time you create a clone in the Start() method, an additional Start is called. W$$anonymous$$ch is logical.

In the scenario where you are wanting transparency, there are issues with the nested Start() calls and the texture updates for the cloned objects.

What I did to fix t$$anonymous$$s was to only update the object texture if the ( gameObject.name == the original gameObject.name), thus preventing the cloned objects Start() method from updating the texture w$$anonymous$$ch allowed my initial object to perform the update to the cloned objects texture.

T$$anonymous$$s may seem a little odd, but I am creating objects dynamically to build a 3D model from a series of 2D image. It works pretty good and now I have transparency to form the 3D shape.
