Atavism 2018.2 is here. With its most demanding feature server-side NavMesh you can do so much, but pathfinding is only part of it. Based on NavMesh graph Atavism can now use full 3d aggro range, so you can fly above the mobs and not cause them to aggro. There is also Line of Sight feature, so if the hostile mob will find obstacle on the way to its target using NavMesh raycast then it won't aggro either.
These features allow you to build dungeons where mobs can ambush your player around the corner. Also, you can have mines and tunnels layered horizontally without issues.
But this release is not only about NavMesh even it's one of the most important Atavisms 2018.2 feature, new Atavism introduces almost 100 improvements and fixes for crafting, admin spawner and more.
As usual full release notes can be found on our documentation page.
