I am having an issue with rendering displacement with the latest Vray and Maya 2016. I have 5 tiles and when I render my scene I can see that the negative values have been clipped. Have you come across something like this and what is the solution.

Just saw your reply. Thanks! I just changed the negative one to -1 and it worked.
It seams vray needs special attention when it comes to multi-tile displacement.
