I need all of my trees to have colliders on them, but I can only get it to be solid if i drag a tree from the project veiw. When I check he tree colliders on the terrain window to on it doesn’t make any difference. Suggestions?
For some reasons, the trees for the terrain have no collider so it is up to you to add one.
Simply create a prefab, place one tree, add a collider like a cylinder and drag the object to the prefab. Then add that prefab in the place trees section of your terrain editor.
Now your trees should have collision.
Here’s a video to show you how:
