Why when I use blender trees in unity terrain they look small and fat?

I exported the fbx of trees and when I go to terrain and trees they look horribly fat and small but when I place the tree as object on the terrain they look good, and I don’t have any window to change its measures

If you export as .3ds this can solve problems

Do your blender models have scales applied to them? If you’ve scaled your trees in Blender and exported them without that scale applied, then they’ll probably be fat and small in Unity.

Go back into Blender, use Control-A to apply scale, then re-export your FBX files and see if they’re still not scaled correctly.
