Normal map artifacts after exporting low poly mesh from zbrush

Lance_Bot

Hello guys.  I recently finished a new character and have been in the process of posing it.  I imported the low poly mesh as a obj into zbrush from maya, posed the character, brought it back into maya and reset my smoothing groups.  This process caused artifacts on my normal map to appear however.  I'm going to just properly rig the character in maya to work around this, but ive been scratching my head as to why these artifacts appeared in the first place.  I think posing in zbrush is pretty common practice, so I'm wondering if anyone has any ideas as to why this might be happening.

Don't change smoothing groups after posing keep em the same

maya automatically updates the inner triangulation of faces, it happens on the fly andprety quickly (millimeters of change) while max for instace eeps thesame iner triangulation stable for much longer. if you triangulated your mesh prit to posing (yep it sucks) the amount of artifacts should reduce drastically

Thanks for the response guys.  Much appreciated.

it seems like a combination of rebaking and using a triangulated mesh for posing did the trick.
