polygroup seams problem

ZBrush Usage Questions
#1

I’m drawing a blank but I know I’ve seen this work yet I can’t remember how to do it for myself…

If I have a single mesh, say a man, and I create polygroups at the low subdivison and then split the groups so I can subdivide each polygroup/subtool as I need to; when I subdivide each separated subtool, I lose the seam where each polygroup was originally attached to each other. And when I merge the subtools, the seams are quite visible.

I saw, somewhere, a button to click that when you separate polygroups of a single mesh into separate subtools, you can retain each seam/joint so that after you subdivide and work on each subtool, you can then merge it and it’ll look like one complete mesh and NO seams.

I’m embarrassed to even have to ask for the assist but I just CAN’T remember how it’s done…any help would be appreciated!

I’ve attached a jpg to illustrate the problem.

In the top shot, I’ve made two polygroups.
In the middle shot, I’ve done a group split to separate the polygroups.
In the bottom shot, I’ve subdivided both but there’s now an obvious seam between the two and even if I merge the subtools, the gap remains.

Does anyone know how to keep the seam edge between polygroups so that subdividing won’t affect them from ‘blending’ and looking like a seamless mesh even when in different subtools?

Thanks!

hi wizzie14u if u export it as obj. then reimport it from the import menu with merge and weld setting option should cure seam problems

But, I’d like to subdivide each separate polygroup after splitting the groups. As soon as I subdivide, the seam appears. I need to know how to keep the seams intact even after I create polygroups, split them into subtools, subdivide and sculpt and then merge…

I don’t think what you’re suggesting would work for that…

I found the button and figured it out…

Thanks though!

Is it a secret? :slight_smile: how did you solve it?

LOL no it’s not a secret…

It’s the crease button in the Geometry tab…

You have to remember that people are doing searches on these forums for solutions to their problems. Saying “I found the button and figured it out…Thanks though!” doesn’t really help them out does it. That is probably why oofnish was asking you “Is it a secret? :slight_smile: how did you solve it?”
