GUI buttons without borders

Hi there, I am in the middle of creating a GUI for my app. I currently have a bunch of functional buttons which have borders with shading, however I am looking to have an interface more similar to say Starcraft’s in game GUI. Basically a texture with mapped zones for buttons.

I have seen a few Unity GUI’s with buttons that were just parts of a larger texture and they worked well.

Does anyone know where the functionality for this is??

Thanks

EDIT: I am using Playmaker to prototype this project. Am I limited by using the Playmaker GUI functions?

Use a GUISkin, and assign textures to the buttons, fields, box’s , etc… that way they wont be using the default unity borders, but only your texture.

I am toying around right now, if you change the GUISkin images / textures , it wont have borders at all .

I just created a circular button in photoshop , with transparency , brought it into unity , circle button , no border.!

You must remember to do this with the various settings like Hover , Active etc
