Problem with displacement on instances

[nikand]

Displacement is not working on instances in RT gpu/Cpu.
Its only displacing one of the instances.
Displacement in material or VrayDisplacemodifier.
Vray adv it works.

I'm testing different situations with RT, displacement and instanced geo to see what is working and what is not.
V-Ray Displacement modifier added on manually instanced objects works fine in RT CPU here. The same setup but Displacement from material works only on one of the instances.
Instancing geometry with V-Ray Instancer for an example doesn't work with Displacement from material or V-Ray Displ. modifier, which is logged as a bug in our system.

How do you instance the objects in your scene?

In this scene I manualy dragged new instanced objects where I wanted them. Displacements came from material.
I'm pretty sure I tried putting a vray displacement also that didn't work, but maybe I only tested Rt gpu on this on.
