I know this post is kind of old, but did you ever figure out what to do for this fabric? I've run into the same problem (making a multiplayer style Quarian engineer - the model is virtually identical to Xen's). I decided to go with black lycra for the base of the suit, but can't figure out what to do about the honeycomb pattern.
Some kind of fishnet overlay? Or maybe just stencil it on? Right now I'm leaning toward stenciling, because trying to do an overlay with two different stretch fabrics sounds like a real nightmare.
If you found a solution, let me know!
