    private Texture2D RenderTextureTo2DTexture(RenderTexture rt)
    {
        var texture = new Texture2D(rt.width, rt.height, rt.graphicsFormat, 0, TextureCreationFlags.None);
        RenderTexture.active = rt;
        texture.ReadPixels(new Rect(0, 0, rt.width, rt.height), 0, 0);
        texture.Apply();
        
        RenderTexture.active = null;

        return texture;
