Issue with LoadLevelAdditive

[Noi14]

I need to load an extra scene (Called "loading") at the "base" scene using: Application.LoadLevelAdditive("loading");
When I set it as:
void Start()
{
Application.LoadLevelAdditive("loading");
}
there is a moment that the added scene is not load, and I see the basic scene. This is very annoying.
If I do:
void Awake()
{
Application.LoadLevelAdditive("loading");
}
NGUI graphics of "basic" scene is in low quality, but I solve the problem of the moment when I see only the basic scene.
There is the same problem(low quality on ngui of basic scene) when I launch Application.LoadLevelAdditive in the previous scene, putting the NGUI panel of the "loading" scene

with DontDestroyOnLoad(gameObject);

I'm not sure if there is a question in there somewhere?

Doing level loading in Awake() is a bad idea. Whatever the script is attached to hasn't finished loading yet. You need to yield WaitForEndOfFrame at least, or just do it in the Update.

Thank you.
I don't understand why I have that problem(Bad NGUI sprites quality) also when I using DontDestroyOnLoad(gameobeject);  to load in the previous scene, in order to when I'm doing access to scene "base" there will be "loading" already loaded

All NGUI does is draws things using a texture. NGUI never reduces the quality of textures on anything. Only your project settings can affect texture quality (being set to 'fastest' for example). Aside from that, I have no idea.

I've solved problem using GameObject.Find ("LoadingCamera").GetComponent< Camera > ().enabled = false;

If I disable camera the problem no occurs, if I also destroy UI ROOT I will have that problem.
