[Usive]

I am trying to make eye textures using this tutorial

But I run into an issue with the layering masks. It says that I need 2 circular ones, but I have no idea how to allign these perfectly in photoshop.

 

Please, I would love any help I can get on this.

Perhaps the easiest way that comes to mind is to create a mask on one layer and then duplicate the layer and modify it as necessary to create the second one.  Another way is to create the first one, then select all pixels, create a new layer and fill the selection area on it.  You could get a discussion going in the Building and Texturing forum.  Chosen Few and some of the others over there will have other suggestions.
