It sounds as if we're on a similar track. I'd be interested to hear how u get on. Im a bit confused because the only two ways i know of creating maps in zbrush so far, are group uving and Auv ing, is that a standing for adaptive(?) not too sure, but Ive not seen a useful map come out of zbrush in any tutorial I have seen yet. I hope you are right as from my limited understanding so far, if you uv map everything in maya first then the base level object is going to change anyway once youve done some sculpting, so I think maybe you sculpt, then export the base level objs, uv map, then re-import to z for the displacement map creation. But then.....sigh,...

I havnt looked at the link you sent me yet, ive had two long days at work. It was great last week I had a week off and really thought id made some progress. But off again for the next two days so looking to get stuck back in. Im asking questions on zcentral also, do u post there?
