Problem with mirror (Subtool master)

Hi!

First of all, sorry about my english, i’m going to explain the best way i can. I’m new in the world of modeling and, of course, in the world of zbrush.

I’m following the Erik Keller’s book “Introducing Zbrush 4”, now i’m in the chapter about subtools. The book tells me to mirror a dragon’s eye with the plug-in Subtool Master. I have installed the plug-in (I don’t understand it very well but i think it works fine with DemoSoldier.ZPR). The problem is that it doesn’t work with my model. I select the eye subtool, mirror it with Subtool Master (like I do before with DemoSoldier’s glove) but there’s no effect on the canvas :S. I have cleared all the existing masks before trying anything.

What could be the problem?

Thanks in advance!!!
