Hi everyone,
I’m searching to enlarge a mesh, but when I use the scale function, my mesh move from its initial position (cf. figure).
A → Is what I want
B → Is what I get with the transform.scale fonction.

Do you have an Idea of a simple way to get what I’m searching for?
Thank you 
You will get this problem if the pivot point for your mesh is not in the center of the mesh. Based on the diagram, it appears that your pivot point for your hex is off to the left (outside) of your hex mesh. Assuming this is the problem, it is best to fix this in the modeling program. But there is a SetPivot script in the Unity wiki. An alternate solution is to make your visible object a child of an empty game object positioned at the center of your mesh. Sizing would be done using the empty game object.
