I have a group of OBJs (imported with vert order and poly groups intact), specifically two upper arms and I want to sculpt one and have it mirrored on the other, but I do not want to combine them into a single OBJ, because I need to export them separately, with their original vert order poly groups still intact.

I have them grouped, but when I go to sculpt mode I only have one OBJ selected, and I can't seem to sculpt anything.

I'm probably missing something real obvious, or maybe trying to accomplish something undo-able.

Any insight is appreciated.

    $\begingroup$ You can only edit one object at the time (grouping does not make them one object, they are still separate). In the outliner expand the group and select the object you need to edit, then press tab to enter edit mode. $\endgroup$ – user1853 Sep 17 '17 at 11:57
  • $\begingroup$ I'm looking to sculpt not edit, but I assume the same applies. If I combine both objects into a single object and then sculpt them as such, will it keep the vert order and poly groups intact(with the same internal names), so that I can save the file, delete all the points on one side, export, reload the file, and repeat the process for the other side? I need to have a mirrored sculpt with all internal names remaining the same, and still be able to export as separate OBJs. $\endgroup$ – Jason Weiesnbach Sep 17 '17 at 12:10

Okay a little trial and error, and I've figured this out. I need to export both objects together from the original program(not Blender), keep the vert order, and poly groups intact. Import into Blender, still keeping everything intact.

Go ahead and sculpt it as I normally would. Save the file, and delete one half of the object, and then export that(also keeping vert group order, and poly groups). Do NOT save. Close the file, open it back up and delete the other side and export. I now have the original two models, right and left, with all internal names intact.
