PNG texture visualisation problem on GUI

[Trufiadok]

I'm trying to create a camera plugin with target textures layer. The rendered camera image is displayed, but the texture overlaid is failed.

In Unity3D working, but in KSP doesn't. On left side of simple camera picture visible the failed and on the right side what i want it.

What could be the problem?

        private void OnWindow(int windowID)
        {
            GUILayout.BeginHorizontal();

            // Close window button
            if (GUI.Button(new Rect((renderSize.x + 2 * windowBorder.x) - 20f, 3, 17, 15), "x"))
            {
                clcWindowActive = false;
                // This will hide the TurnOffCLCEven event, and show the TurnOnCLCEvent event.
                Events["TurnOnCLCEvent"].active = true;
                Events["TurnOffCLCEvent"].active = false;
                clcWindowActive = false;
                OnSave(nodeInner);
            }

            GUI.DrawTexture(TexturePosition, _textureBackGroundCamera);

            //if (Event.current.type.Equals(EventType.Repaint))
            //    Graphics.DrawTexture(TexturePosition, Render(), null);

            GUI.DrawTexture(TexturePosition, texLEEHUD);

            //Yoffset = 0;
            //Rect inputRect = new Rect(20, 40, 40, 20);
            //AddOutputValue(inputRect, "eePosition", eeCamera.transform.position, 110f, 110f);
            //AddOutputValue(inputRect, "eeRotation", eeCamera.transform.rotation.eulerAngles, 110f, 110f);

            GUILayout.EndHorizontal();

            GUI.DragWindow();
        }

Problem solved. Bug was in load function of PNG.

old code: tex = new Texture2D(2, 2);

new code: tex = new Texture2D(2, 2, TextureFormat.ARGB32, false);

I have another problem: On the rendered camera image "Camera 01" layer haven't got texture. I fill failed area with pink color.

I used camera renderer routine from @RasterPropMonitor plugin.
