Help with the disp vs Uv interpolation

[system]

Hi guys !
i was sculpting a head for a project when i found myself in this issue so any one can help plz !

• i started my work with a prety lowRez model and cheked On the SUV in Zbrush
  -after the sculpt was almost done i’ve exported my level 2 geometry and generated the disp map with “displacement exporter” …until here evthing is Ok
  -the trouble comes when i attempted to assign my disp map in Maya/Mentalray…: the Disp comes with a sort of UnInterpolated geometry ! even with soften normal or mesh smooth ive got the same result
  -but when i converted the geom to SubD everything works Ok even when converted back to poly evrythng works fine …
• i’ve noticed that Uv’s interpolations when smoothed in maya was not the same as my level 2 exported form Z
  -the bigger problem is that i need to stand in lowRez model to finish the rig an unfortunally my RenderEngine dont support Maya SubD:mad:
  here is the issue more explained

It’s my understanding that the OBJ you bring into Maya should be the same LOD as the level you used to generate your displacement map in ZBrush. So if you’re using lvl 2 to make your map, and you’re starting with your lvl 1 basemesh in Maya, there may be interpolation problems. But I’m no scientist and I could be completely wrong
