Navmesh doesn't show up even though it's working

My nav mesh is invisible, although it's working as intented. For example i can add Nav Mesh Obstacle component to my "wall" and agent takes wider route after baking. So seems like everything works fine, but for some reason I can't see these blue multiple ares created by navmesh.

I've tried several solutions I've found in Google, but unfortunately without success.
I'm attaching a file where you can see that the scene looks like there is no navmesh at all, although it is there...
How can I resolve this problem?

 

The NavMesh is only visible in the editor when you're having the Navigation tab open and active.

 

How about that?

 

Huh, that's strange. Is that happening in any scene in this project, or only in that specific scene? Just quickly create a new scene and bake a Navmesh in it.

 

Is the ground set to static?

 

I've just tried it and Navmesh is still invisible.

It wasn't, and after i checked it, navmesh appeared for like 0,2 sec and disappeared again.

This problem isn't so important for me, but seems weird that it just won't show itself lol.

 

Update
Turning Gizmos on finally resolved this problem for me, thanks for your replies.

 

newbie and none of my attempts are showing the blue mesh. I changed static to navigation, have navmesh display to show on checked, baked it, navigation tab is clicked. nothing.

 

I've just gone to re-bake my navmesh and have noticed that I can't see it either, in Unity 2019.2.

 

I had the same problem.
As Yanurary said, turning on gizmos helped.
What I did was IJust click the gizmos button in the editor view (top) and swich to the navigation tab afterwards.

 

Well now I feel silly lol. Done the same thing - I hadn't realised the Gizmos button was toggled off <facepalm>

 

It was my first time using navmesh, and its was "not working", i removed it, downloaded again, 3 hrs later i figured out that the navmesh file was created, GG. But i coudnt see the "blue" shape yet... gizmos was deativated. Thank you!

 

gizmos?

 

if it's not working you can reset legacy bake settings by left clicking nav tab, my terrain wasn't baking so i reset and i worked

 

Yep just turn your gizmos on and it should work ..........it worked for me

 

FYI - I discovered today that navmesh shows in editor -> scene view fine but not in when in prefab view

 

Thank you!

 

But please I have another problem when I try to paint textures into a terrain it produces white edges around the painted texture

 

Oh my gosh!
I had the same problem too. <doublefacepalm>

THANK YOU.

 

Yeaaaaap, it was toggling GIZMOS for me, too. Don't I feel stupid. Thanks, all

 

Yes it help you were right

 

SiIMPLE SOLUTION :
Turn on GIIZMOS

 

sad thing for me, same problem , but had my gizmos on , still I can't view the blue stuffs

 

Haha had same problem

 

Thank you!!!!!!!!! Today I had the same problem hahaha

 

You are a Master

 

Hey everybody,

in case someone stumples over this thread:

There are two possibilities for creating a nav mesh:

1. The old way : Open Navigation Window -> Select the object tab -> Select the gameobjects in the hierarchy and mark them as static and walkable -> Select the bake tab -> Click bake
2. The component way (new way) : Attach a NavMeshSurface component to any gameobject and press Bake.

How do both ways seem to work:

1. The old way:
Each gameobject that is marked as navigation static will be considered part of the navmesh. Controlling the areas allows for including / excluding gameobjects from baking.

2. The new way:
The NavMeshSurface Component allows to create a Navmesh depending on the settings made in the NavMeshSurface component. One can either define to respect

• All Gameobjects
• The Child Gameobjects of the Gameobject where the NavMeshSurface is attached to
• GameObjects that are within a defined Volume

Furthermore one can restrict the selection of gameobjects by grouping them to a custom Layer

So far so good but what to do if the navmesh doesn't appear?

Here are things I found in other threads:

• Check the gizmos
• Check if objects are marked static ( Only works for old way )
• Check the parameters set in the bake tab of the navigation window ( Only works for old way )
• Check the parameters of the predefined agents in the navigation tab ( These are used with the new way )

One thing I noticed however that in my version 2020.3.15f there also exists another issue which I haven't found as answer in any other thread.

It seems that the navmesh only gets updated in the scene mode. It does not work in prefab mode. One can see the navmesh by

• opening the navigation tab ( Only works for old way )
• Selecting the Gameobject containing the NavMeshSurface component ( Only works for the new way )

in the scene as well as in prefab mode however hitting bake again, doesn't update the visual representation of the navmesh until the scene mode is next visited.

I hope this helps anyone stumpling over this thread.

Greetings

 

1. Set your environment game objects to static.
2. Unpack your environment prefab. If possible
3. Enable Gizmos in the scene view.
4. Make sure your navigation window is currently selected.

 

Heah guys just adding to this maybe a bit late but I too suddenly had disappearing nav meshes however the fix was simple but maddening - I HAD INADVERTANTLY LEFT THE SMA:LL PADLOCK ON IN THE TOP RIGHT HAND CORNER OF UNITY WHEN LOCKING A PREFAB TO ADD A SPRITTE FOR INSTANTIATION - just turned padlock off to stop locking it and all my Nav Mesh Components came roaring back into view, phew thought id lost them all for a moment, hope this helps anyone with similar scary moment mid game build!
