Trees in Unity terrain/agent and agent/agent avoidance problem

(I use the free version of A* Pathfinding project for testing, before i purchase the pro version.)

Hi,

is there a possibility to avoid stucking in the Unity terrain trees? The trees have colliders, because the agents stucking (or this isn’t a prove for that?). The grid simply ignore the trees, because these are a part of the terrain (the terrain cannot be ignored) and there is no own layer for the trees.

Am i have to put trees as prefabs on the map instead of the terrain editor trees? Or is there another solution, probably the RVO could solve this problem? I have the same issue with agent collisions, they just don’t see each other. Is in this project probably a solution for this problem?

Thanks for your time.
