An Area in a NavMesh is simply a part of the mesh with a cost. You can find Area tab in the Navigation window. As you can see there are 3 built-in areas in Unity. The cost of an area plays a decisive role in navigation as our agent notNavMesh agent ; will try to follow the path that has the least possible cost.
Building Off-Mesh Links Automatically
Off-Mesh links are links that creates a connection between two different meshes. In other words you can jump between multiple meshes using these links. They can be generated automatically or you can also generate them by off-mesh link component if you want a better control over the navigation behaviour.
Assign the respective GameObject in it. If the link you created is not a valid link both ends are placed on a mesh surfacethen the color of link will turn into gray rather than black.
If you opt for automatic link generation, Unity will create every possible link to connect meshes which might not be ideal for your case. If you want a specific route to be followed you can use Off Mesh Link component. But what if we have a moving object that we need to be a part of our navigation mesh?
Check the carve option and you should be seeing a hole in the mesh. This is where I end this post and you start experimenting on navigation meshes. Got an Idea of Game Development? What are you still waiting for? Contact us now and see the Idea live soon. I work with Unity Engine.

I have set up Unity navigation meshes four planesnavigation agent sphere and set up automatic and manual off mesh links. It should now jump between meshes.
It does jump between meshes, but it does that in straight lines. In other words, when agent comes to an edge, instead of actually jumping up like off mesh link is drawn it just moves straight in line but a bit faster. I tried moving one plane higher than others, but sphere still was jumping in straight line. Is it supposed to be like this? Is it possible to set up navigation to jump by some curve?
Or should I try to implement that myself? Its recommended to solve your problems via animation. Just create a Jump animation for your object, and play it at the correct time. The position is relative, so if you increase the Y-position in your animation it will look like the object is jumping.
I came by this question, and had to dig through the Unity sample.
How to trigger a Jump on an offmesh link
I just hope to make it easier for people by extracting the important bits. Finally, when the transition is complete, you need to tell Unity you've moved the agent, and resume normal navmesh behaviour. The way you handle link logic is up to you. You can just go in a straight line, have a spinning wormhole, whatever.
For jump, unity traverses the link using animation progress as the lerp argument, this works pretty nicely. Not sure what version of unity you are using but you could also try this, I know it works just fine in Learn more.Off Mesh Link components.
Place the two game objects to the start and end points of jumping, and set the start and end points of Off Mesh Links components to the two empty game objects.
After that your character will jump up to the area you will see the arrows in edit mode. Check if you set to true the Hight Mesh checkbox on Navigation.

The ground where the NavMeshAgent stands is in layer 4. But the Agent is not jumping in the first place. But when I don't used the OnCollisionEnter function it jumps. But I need some function to return it to the initial state. I tried a print "something" inside if statement of OnCollisionEnter function and it prints it as soon as I hit Space. That if statement should have executed when the object jumped and collides with the ground.
As you said, the function is called as soon as you hit Space. That's why it doesn't work because isKinematic is then instantly reset to true before your character can even start his jump. You must have another object other than the ground that is in layer 4 and is colliding with the player. Instead of using the layer, I would give the Ground object and any other similar object a Taglike "Ground" for instance.

The two most common ones are: Drop-Down and Jump-Across. In order to find the jump locations automatically, the build process walks along the edges of the NavMesh A mesh that Unity generates to approximate the walkable areas and obstacles in your environment for path finding and AI-controlled navigation.
More info See in Glossary and checks if the landing location of the jump is on NavMesh. If the jump trajectory is unobstructed an Off-Mesh link is created. First, the objects in the Scene A Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info See in Glossary where the jump can start from needs to be marked.
When ever you change the scene and bake, the old links will be discarded and new links will be created based on the new scene.
3 Advanced NavMesh techniques to improve Unity Navigation

Publication Date: Is it possible to add jumping and falling to my AI while still using the nav mesh system to walk around? I am on Unity 4. Generally, the NavMesh is only used for pathfinding. Anything else you want your AI to do, you have to make it do yourself. Jumping isn't an issue. Actually turning towards target and knowing when to jump and when to walk around is the problem.
I know it can all be done but I was looking for methods. I could eventually throw something together though. If you can't bake off mesh links, then pathfinding will not take into account "jumps". It's as simple as that. Off-mesh links are just another part of the navigation mesh, nothing special. If the mesh is there How could I go about allowing the AI to drop from ledges without running all the way around? You could create your own off mesh links using static trigger colliders.
Let's call them jumpzones for convenience. Each jumpzone can have an associated animation jump, drop, etcdestination, and travel cost.
When evaluating a path, check the nearby jumpzones. If any of them will get you to your goal faster, navigate to the jumpzone instead.
The jumpzone script can automatically trigger the animation for any characters that enter it. When the animation is done, just recalculate your new navmesh path from the point where you ended up.The NavMesh A mesh that Unity generates to approximate the walkable areas and obstacles in your environment for path finding and AI-controlled navigation. More info See in Glossary Link component is not in the Unity standard install; see documentation on high-level NavMesh building components for information on how to access it.
This link can be from point to point or it can span a gap, in which case the Agent uses the nearest location along the entry edge to cross the link. To use the NavMesh Link component, navigate to GameObject The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces.

The start point of the link, relative to the GameObject. Defined by XYZ measurements. The end point of the link, relative to the GameObject. With this tickbox checked, NavMesh Agents traverse the NavMesh Link both ways from the start point to the end point, and from the end point back to the start point.
When this tickbox is unchecked, the NavMesh Link only functions one-way from the start point to the end point only. The area type of the NavMesh Link this affects pathfinding costs.
