Wanted to let you all know that I have converted and added all the ZBrush bruses from before into a nice Photoshop Brush set as well which you can download from here:
It's right under the "New" image.
Simply unzip the .abr file, and drop this brush set into your /presets/brushes folder under photoshop and inside photoshop just load the brushes and you should be set.
I didn't do any modifications to the brush properties, but I'd suggest messing with the "Brush Editor" "F5" and adjusting things like diamater, scatter, spacing, etc. to make the brush work really well and to meet the needs of your particular project.
Lots more to come from TextureArchive.com
