Using GoZ with lancewood

I had some trouble exporting with Goz initially because Zbrush refused to find the application location but I used this link to help and reinstalled some of the goz plugins and then it started working:

Also need to put foliage on the lancewood, I have my leaf alpha and I need a bark texture for the tree. I'm looking at this forum for Maya because it has some interesting points on how to make realistic foliage: link

This will include editing my vertex normals on the tree foliage so that they will look less like planes -bending normals  - this helps to light them at a different angle and makes them look more leaf like, I also have to make the backface for the textures manually so that they don't get blacked out.
