Vray rendering displacement

Hello,
Started work on rendering one of my assignments due Tuesday only to find one of my models is being warped by Vray during renders.
It’s moving around my walls and window and pretending some faces aren’t even there, the walls have all been constructed as solids and although some components are still blocks from Archicad I don’t see that as being an issue.
Any help would be greatly appreciated



.

Figured out the issue,
Had messed around with the texture’s displacement causing it to act weirdly outside of Rhino.
Hope this helps anyone else that made the same mistake I did.
