How to get an actor to scale when mouse over?

I have three rotators that are child to one rotator. I want these rotators to either scale up by a small amount when i mouse over, or they get highlighted. 1 of these rotators us small, one is normal and one is large. how will i get them to scale respectively?

I would do it like this:

and just remember to set the Enable Mouse Over Events check box, that’s in the Mouse Interface tab, to true in your Player Controller

Thanks. I’ll try this and get back to you if i need help.

Thank you this worked perfectly! all i had to do was change some scales around because they were clipping through the each other and then I couldn’t click them any more. Cheers!
