"Clear trees" tool doesnt work in my scene.

[0Anton0]

I can't remove the trees around the GeNa road on my scene. Everything works fine on the test scene. My Terrain is quite large, but I don't think that's the problem. In what cases can this tool stop working?

Are these trees a part of the Unity terrain system or game objects? 
How are you trying to remove these trees?

These trees were drawn as part of the Terrain, not as GameObjects. I used the clear trees extension in the road spline.

Can you please tell me what Unity version you are using and what GeNa Pro version you are using? 
 

[0Anton0]

GeNa 3.5.0-c5 Unity 2022 3.8f1.

Can you please try to upgrade to the latest, you are a few versions behind.
