!IsNormalized

Hi Guys
I'm getting this console error and I don't know how to get rid of it Would someone be so kind as to help a noob out?
Message:
!IsNormalized (normal)

sub message: (Actually there are 2 errors, line: 49 and line: 77)
Assert in file: Plane.h at line: 49

I can't think I've done much different except I'm regularly replacing an imported fbx scene as it is updated in Cinema4D

Thanks Joachim
Its qute a big folder, probably about 80mb zipped. The error doesn't seem to prevent me from building the level so I'll keep an eye on it and submit it when I get chance.

I just had the same error on the latest 2.0.2 release. It appears that the culprit is the Spotlight object which does not like range=0. Changing it to 1 fixes the problem.

Hope this helps!

Hi Loachim,

I recently got the iphone extension for unity. The first thing i did was decide to convert the the Lerpz 3D example so that it can run on iphone.

The first time i build it it had heaps of errors. I fixed them by using #pragma strict. And explicitly creating variables of the correct type, instead if just inferring the type from the \"Get\" functions.

Like this:

function Start ()
{
var foo : MyScript = GetComponent(MyScript);
foo.DoSomething();
}


Now everything compiles fine and runs in the preview window on my desktop.

However i get the following assertion:

!IsNormalized (normal)
Assert in file: /Users/joe/iphone-clean/../Runtime/Geomertry/Plane.h at line: 67

The console is bombarded with this message all the time when the app is running.

On my desktop it still runs, when i deploy it to my iTouch it gets to the menu, then after hitting play it takes ages and just resets the iphone. ( maybe running out of memory ? )

I have tried to minimize geometry by removing allot of the level geometry leaving on Lerpz on his 1 platform. Reduced overall filesize by heaps, but still crashes the iphone.

Any ideas ?

Kind Regards

i get exactly the same error when i use a projector component in an iphone scene.

 

It's easy, your camera near clip is too near. Mine was at 0,0001. I changed it for 0,01 and it stopped spaaming !IsNormalised(normal) in console.

If it doesn't work look for other 4 decimal value near 0 in lights or cameras.

I got the same error when adding a SpotLight to a GameObject. This code generated the error:

Code (csharp):

1.  
2. GameObject spotLight = new GameObject("spotLight");
3. spotLight.AddComponent<Light>();
4. spotLight.light.type = LightType.Spot;
5. spotLight.light.range = 1000;
6.  

But this did not:

Code (csharp):

1.  
2. GameObject spotLight = new GameObject("spotLight");
3. spotLight.AddComponent<Light>();
4. spotLight.light.range = 1000;
5. spotLight.light.type = LightType.Spot;
6.  

 

I'm still learning, and am running into this as well.

I have a terrain, a camera, two spotlights following two wheels rolling over the terrain.
Immediately, even when setting things in the editor and not just when pressing the test play button, I get dozens of messages saying:
!IsNormalized( Normal )
and the log claims an assertion:
(Filename: /Applications/buildAgent/work/71ca6fec1b41cc30/Projects/../Runtime/Geometry/Plane.h Line: 71)

I presume some vector ends up being zero somewhere where it shouldn't, but how? What? I tried everything. When I even so much as touch a camera or light, this comes up. What could it be?

 

...oh, and I also get this:
"!IsNormalized (normal)
UnityEditor.DockArea:OnGUI()"

and then the same assert as above, claiming there is an error "in file"?!

 

Funny how this bug with spotlights still not fixed.
