Topic: What is the fastest way to convert Renderer Texture to file store state or Wifi pushed.

[EloiStree]

Is GetRawTextureData better that Marshal Copy

MemoryMarshal.Cast<Color32, byte>(colors).ToArray(); ![Uploading image.png…]()

 public byte[] ConvertToBytes(Color32[] colors) { return MemoryMarshal.Cast<Color32, byte>(colors).ToArray(); }
 public Color32[] ConvertToColor32(byte[] value) { return MemoryMarshal.Cast<byte,Color32 >(value).ToArray(); }
