Every time I try to make a normal map for this texture I get banding that only appears in the green channel. I am just trying to transfer the tiling normal to a flat plane. I'm still fairly new to Zbrush, so I'm assuming that I'm just forgetting something. In the pic, you can see the horizontal bands going across the map. The b&w part is the green channel. There is no sign of the banding in the other channels.
I would really appreciate some help. Thanks.

As for the banding, what settings are you using when creating the map?
