NavMesh not including all the surfaces - unity3d

I have a level made with pro builders and at that level there is an agent who attacks the player. The problem is that when i baked the navMeshSurface i did not include all the walkable surfaces. See the image below :-
I am now really frustrated with how to solve the problem, i tried nearly everything. I tried changing the layers and also tried placing other game objects over the area which are not baked. But, it did not work.
Please tell how can i include all the surfaces in the navMeshSurface.

make sure you have selected all the blocks, because if you didn't it will only bake the ones that are selected.

Why do my 2D objects not collide in Unity despite that the layers are set correctly?

I have a platform that I need to flip the direction of when it collides with an object. The platform as well as its child objects belong to the layer "FlyingOrPlatform". The object that the platform collides with should belong to the "GameControl" layer. But if i set it to that it doesnt collide with it.
If I set the object that the platform collides with to either the "Player" or "Default" layer. Then it works completely as it should. But I wish to use the "GameControl" layer.
I have tried where I save the scene and the project, as well as restarting the editor.
I dont see what should be wrong with my layer setup. Any suggestions?
In my script for reversing the platform direction there is no layer check, it does check the tag but I ensured that the tag is the same when I switch between the layers. I just use Unity's built in OnTriggerEnter2D lifecycle method. Have tested with OnCollisionEnter2D and OnTriggerStay2D as well, same result.
Here is a link to a video demonstrating the issue, as well as a screenshot of my physics2D settings below. In the video I first show how its supposed to work, and then I switch the object the platform collides with to the GameControl layer, after which it doesnt work.

Physics2D settings:
From what I can tell this appears to be an issue with the Physics2D matrix in Unity that occurs from time to time. A couple of other people have written similar things on other forums.
Among others this reply had a similar issue:
For lack of better, I found a work-around by using the "Ignore Raycast" layer instead of the "GameControl" layer.
I have reported it as a bug to Unity.
EDIT:
Here is the reply I got from Unity.

Shadows doesn't disappear

I made an endless runner game where the horse runs in a canyon. So i noticed that in the walls makes shadows on theirselves so i wanted to remove it beacuse it's ugly. So my problem comes here, how can i remove that shadow even if i disabled the shadow casting from the mesh renderer of that walls? I also tried to place a light point near the walls but it still don't work. How can i resolve this. I attach a photo so you can understand what i am talking about.

Those are most likely just objects interacting with a directional light in the scene. Instead of shadows, those are just sides of objects that as less illuminated.
I can throw in two potential solutions:
Solution1:
Go to Window->Rendering->Lighting, select Environment, change the Environment Lighting Source value and modify the color values to your liking.
Solution2:
Add a material which changes how the objects interact with lighting. One option could be to just add a standard material with some emission.

How can I achieve a node that will desaturate everything below it?

I am building a game where everything behind the player is greyed out as if it lives in a memory. But I don't know how I can achieve this effect. Is this where shaders are being used for?
Now I can create a SKLightNode to create the lighting and make it dark around the edges. But I like to field of view for the character to be 120 degrees. Everything outside of that angle should be greyed out.
Of course in the future I like the view to be blocked by obstacles but that is outside of the scope of this question.
A desaturation shader for SpriteKit can be found at my blog post on that subject. Note that this works in terms of an input texture, so you may need to adapt things to work on top of a tiled background. Also note that there is a new iOS 9 API to support capture of the output of a whole node, which may be useful to you in implementing this.

Textures to Object in Unity / Vuforia

I'm trying to do some Augmented Reality in Unity using the Vuforia plugin. I've managed to get everything working (I'm using a 3d model of a car), only the position of the car relative to the marker is wrong when I come to preview it (click the 'Play button at the top and watch through the computer's camera - is 'preview' the right name for this?).
It should be sitting on the the marker in the center, but instead it's floating above the marker and off to the side by quite a bit. The positioning is definitely right in the program itself, so I'm not sure why this isn't reflected in the preview.
Also: at the moment the car is simply an untextured grey object. I realise the textures are included in a subfolder, however I can't drag the entire car's folder (including the Textures subfolder) into the ImageTarget, only the .3ds file itself. Does anyone know how to apply the original textures to the car?
Thanks so much for your help in advance!

Well, to start answering your question about the drifting away part, you've probably got a Rigidbody attached to your Car? Well, if that's the case, then Go to the Inspector where the Rigidbody is and you'll see constraints.
To avoid it floating off, you might want to check Freeze Positions for whichever direction it needs. Probably Y axis.
Now, I'm not entirely sure if you're using Vector.AddForce to move your objects, but if you are then just check if your car can move if you've put all constraints on.
If you can't then in your code trying using Object.Rigidbody.SetActive(true) when you need it to start moving, and Object.Rigidbody.SetActive(false) when its done.
On the other hand, if you aren't using Vector.AddForce() then remove Rigidbody component if you've used it.
As for the material. If you've got the material in your folder that you've downloaded then just drag and drop it into Assets. Now sometimes your car may be one solid mesh, but some times it may be multiple meshes. So which ever the case. Drag the material from your Assets onto the Hierarchy panel over your car mesh/meshes and it should turn into that color.
Hope it helps. :)

Shadows going through objects

I'm new to Lighting in 3D. Just started working with Unity3D. I was creating a sample for myself to test shadows and there is a problem.
As you can see that i have created two simple walls with two cubes. Also I have setup a directional light. Let's go the backside of the walls to view the problem
Technically the front wall should be blocking the shadow of the back wall. But it is not. I have painted a read line to show that where the shadow of front wall is overlapping the shadow of the other, meaning going all the was through the wall. Why is that happening. Help please...
set your shader to DIFFUSE. i have the same problem and solved this. my spotlight is passing thor
that is interesting indeed, i have used unity3d for 5 plus years and never seen or noticed this. however, this might seem like a weird request, could you set the ground and the two cubes to bumped diffuse and make sure the cubes are touching the ground.
Since the shader that is used might allow shadows to pass, secondly, could you go to player settings and check if you are using forward of differed rendering, since their lighting techniques are very different they might have different results.
but all in all, best guess is that the shader you are using allows shadows to pass.
