How to make transparent mesh in zbrush

Hi everyone, i am new to this Zbrush forum and i would like to ask for some help regarding the quesition below,
How to make a transparent shader for the mesh im working on with image plane behind it.
Although i have tried to pick the material that has transparent option and as i ranked up the transparent slider but the mesh still doesn’t appear transparent on the screen.

Thanks a lot for sharing the knowledge.

there is a 'transp" button on the right shelf

Hi goast666, just wanted to say that i appreciated for your response. But the transparent button seems to work only with multi objects in Subtool. I was hoping something more like Maya that we can model the mesh with wireframe on with the image plane right behind it. It used to work like that in Zbrush 2.0 though!
However, i have found this link is also really helpful and would like to share it back with you. But then i don’t know where is image plane in Zbrush 3.1. If you happen to know then would you please pass on. I will find it myself too in the mean time. Thanks
