AI Navigation

Jun 13, 2016

How to reproduce:
1. Open the attached project (TreeTest.zip)
2. Open scene Scenes/SampleScene
3. In the Hierarchy window, double-click on the GameObject "TreeLocation" to observe the Trees in the Scene view
4. In the Hierarchy window, select "NavMesh Surface"
5. In the Inspector window, under the NavMeshSurface component, select Bake
6. Observe the NavMesh in the Scene view

Expected result: the Terrain Trees are taken into account in the NavMesh
Actual result: the Terrain Trees are not taken into account in the NavMesh

Reproducible with: 2019.4.36f1, 2020.3.30f1, 2021.2.13f1, 2022.1.0b9, 2022.2.0a5

Is this bug real ? i can not understand how we can do big "nature maps" with thousands of trees, rocks,... were its imposible to put every single tree or rock manually.

How are we supposed to do this?

I'm freaking out that this bug exists and that it's been around for so long!!

I would like to +1 getting this prioritized. It's crazy that the new version of navmeshes has a regression as big as this.

Also leaving this here for everyone with this issue (which are gonna be a lot of people now that it is forced with the newer versions of Unity).

This guy made a really good fix:

Please fix this issue.
From Unity 2023 forward, the new AI naviagtion systems forces you to use NavMesh Surfaces, instead of baking it through the navigation window. (Unless you use the obsolute version, which shouldn't be neccesary.)
This means that in the newest versions of Unity it has become IMPOSSIBLE to bake terrain trees, without using outdated feautures with a warning that they will get deleted...
