Zbrush polygroup seams issue

Jack03

Hi all, I been looking at the forums for many years, just never posted.  anyways, I'm having an issue, which typically won't effect our game  to much. But I like to see if there is a way to fix this if possible.   I have characters, that are split into polygroups, mainly to hide , pieces , like head, etc for First person view . Which again you won't see it so won't matter much, but where I make the polygroups, you can see the lines.  So for example, when I make a polygroup , so I can hide the head, around the neck area, is where the line is.  I plan to use the full character for third person. So I was wondering, and I'm sure there is a way, I'm just not remembering been awhile since I had to split up characters, if there is way to still be able to hide, show parts of the mesh, but still, not show this line... across each polygroup.   Thanks.

Do you mean you see the seams after exporting? This would be due to it disconnecting the vertices along the border, and can be prevented by disabling Tool: Export: Grp

Ya you can see the seams/Lines where polygroups are.  in the full character in MAYA, Unity etc.  Yes I know its from disconnecting vertices, since I need to be able to hide head,arms etc.  But again I forgot, been awhile, knew there is a way I believe to have this not show, in Unity, Maya etc.   I will give that a try.  Thanks.  Ya had a feeling it could be an export issue. Just wasn't sure, since Zbrush you can do things some many ways. I just forgot how, its been a few years, since I needed to do this.  Thanks!

can you be more clear about what needs to be done, disabling tool? then export group? export using what format, I was using FBX. Thanks.

Tool: Export: Grp is only for the Tool: Export option (obj format). If you're using a plugin to export as an FBX File, then the plugin will have its own options for how it handles polygroups. In that case you may have to post a screenshot showing which options you currently have enabled in your FBX exporter plugin, and any further details about the model (does it have a normal map applied, for example).

I thought that is what you meant under export yes group was selected.  it   still made one mesh  unless I split into sub tools, and then it did the same thing left the same lines.. didn't matter.  I also looked for this under FBX format. only thing I seen for polygroups is setting it to selection sets, materials etc.. guess I could try some of them, never used before.. I also tried Sub tool master, export  But there was nothing in the export that helped as someone else told me to try that.... So for no good.. Can't see to get rid of those lines.  No materials , textures, etc applied.   So no  normal map applied to it. Bare bones. Freshly made. with nothing else added, besides a rig. 

I tried ASCII  instead of  Bin. didn't think that would help. but tried anyways, since I wasn't sure what else to do.
