Resize model in ignition gazebo

edit

Hi all,

I am using ignition gazebo and I am trying to import a model modifying the size of it.

In particular, I am trying to include a model of a tree (like this one to give an idea) in a world, I want to include different trees and have different sizes in order to vary the trees. However, when including the model I am not able to use the <size> tag in the SDF file.

So the question is, how can I change the size of the model that I import?

Thank you in advance for your time
