I've recently tried again a few tests and obtained bad results, even with the ‘42’ setting in Zb. For someone that's inexperienced with Mantra settings/shading the issue seems to have no solution in sight.
If someone is willing to help with a .hip file, if they get good results, I've attached a piece of test geometry with an .exr vector map. At this point I want to see if it's a matter of bad Houdini settings or bad Zbrush map extraction settings on my part.
One question for now: does Mantra make smooth UVs when it subdivides geometry?

@axalon I think you have to keep Subdiv level to your lowest (usually 1) that you've exported as .obj Also, the vd_SUV (smooth uvs) might have to be unchecked. We'll have to wait until someone knowledgeable elucidates us on the matter.

Hmm, after a few more tests and looks at this thread, I think your problem is lack of detail. Increase shading quality for your object from the default ‘1’ to 2 or more to see if it helps.
For me, it seems that no matter what I do I get that faceted result, smooth or no smooth UVs checked in Zb. Can you share one of your .hip file to see if I'm doing smth wrong in H or in Z?
