Breaking straight edges

Hey guys,
these days im struggling with a big problem. And i dont know how to fix it.
I want to get rid of the straight edges on my mesh. I tried really every option and searched for a solution on the internet.
So what I have tried so far:
Exported base mesh with edge loops/creased edges from maya to zbrush to preserve sharpness.
Then I sculpted a little bit detail to the edges and exported a displacement (even vektor displacement map). All what i got were artefacts and disconnected faces...
So my question...is it even possible to achieve this on such sharp edges?


Here is is a picture of what I want to achieve.




Thanks so far.

It's possible, but the limitation with displacement maps is that they require vertices to nudge...as many as there are details in the map, really. Hard edges definitely are difficult to work with. Normal maps might get a better result, (not sure) but I don't think they handle edges very well either.

With the above in mind, have you considered skipping the displacement map and exporting your final Zbrush model to use instead of the original object, assuming it has the shape you want?
