Based on your SBS the helmet looked good in ZBrush. But it seems to have lost some details on your final render. Actually I found it hard to see what it was in HI-Res. Anyway, no hard feelings, because of the lack of time to fix anything before the deadline I'll base my vote on the SBS-version instead.

Dka, perfect. After I read your comment I begin to digg like a fool on tutorials, helps...you know...everything. And, surprise . I discovered that transphering the wavefront object and the displacement map from ZBrush to Max is not enough to keep all details. I have to use also a V Ray displacement map. At this moment dont know how to do it. Never mind. next time. Thanks, man, I feel like Columbus, I see America but I cant touch it.

Very good, the reflection are excellent.
