    Hello, i am trying to convert a texture to byte array and then to string and then save it on firebase and then again fetching it and converting it to texture.
    But right now it is not even working locally. i am trying to convert a texture to byte array using GetRawTextureData and loading it using loadrawtexture data but that is also giving me some random shaded colors.

    Thanks in advance.


    Code (CSharp):
    1. void TheTest()
    2.     {
    3.         byte[] bArray = test.GetRawTextureData();
    4.         Texture2D tex = new Texture2D(2, 2, TextureFormat.RGBA32, false);
    5.        
    6.         tex.LoadRawTextureData(bArray);
    7.         tex.Apply();
    8.         abc.texture = tex;
    9.     }

    I'm facing the same problem here. Did you get to solve it by any chance?
    In my case, I need a byte array from a texture that is being dynamically painted, then feed it to EasyAR.
    I can pass an arbitrary byte array to EasyAR and it represents it correctly. But when I retrieve the byte array from the texture, it always returns me the same shade of gray. From other posts I tried to use Apply() and call it after the Renderer Update, but without any luck.

    void Start()
    {
    byte[] bArray = test.GetRawTextureData();
    string texAsString = Convert.ToBase64String(bArray);
    Texture2D tex = new Texture2D(2, 2, TextureFormat.RGBA32, false);

    tex.LoadRawTextureData(bArray);
    tex.Apply();
    abc.texture = tex;
    }

    Hey, I had the same problem today and for me, the problem was the format.
    Instead of:
    Code (CSharp):
    1. Texture2D tex = new Texture2D(2, 2, TextureFormat.RGBA32, false);
    Try:
    Code (CSharp):
    1. Texture2D tex = new Texture2D(2, 2, test.format, false);
    The goal is to have the same format for both textures, which isn't necessarily RGBA32 as you might think depending on your import settings. If you want it to be necessarily RGBA32 then, you have to check it with a if statement and throw and exception if that's not the case.
    Good luck to you guys!
