vray disp modifier ? seams coming apart

[tom182]

Hi,
I have a box/wall that has a stone texture mapped onto it, am using the vray displace modifier but the edge of the wall blows apart when I up the displace value. I need to get the wall realistic i.e. not flat, any ideas
Thanks
Tom

You might try Seraph's technique as outlined here http://www.seraph3d.com/bricktut.htm

looks like you got old vray? anyways this problem can be solved by checking keep continuity option under 3d displacement options.
