Imported FBX - separates when each subtool is sub-divided

[SharleenC]

Sorry, just can’t work this out even though I’ve looked for answers elsewhere.

I trying to import an fbx file with a view to adding texture maps to it. It’s a female form which is split into subtools such as head, arms, legs and torso. If I subdivide the individual subtools, the geo is nice and smooth but they split apart, leaving a gap inbetween each one. I can then add the texture maps to each individual subtool however I can’t then knit the whole model back together.

I tried using zremodeler brush but couldn’t make it work, looked at bridge brush but I think that’s just for bridging circles rather than irregular shapes.

I’m obviously missing something but help would be gratefully received!

Many thanks

Hi @SharleenC

Turn on Polyframe (Shift+F) and see if each section has it’s own polygroup. If it does, then, before you subdivide, go to “Tool > Geometry > Crease” and click “Crease PG” button (crease polygroup borders) for each subtool. You can then subdivide and you won’t get the gap. If you have to stitch everything back together later, you can use “WeldPionts” (weld identical points) in “Tool > Geometry > Modify Topology”.

Great - thanks ZBER2!

The gap is reduced but not gone but we’re getting there! I tried on this OBJ rather than FBX (not sure if that makes any difference at all) but still get little gaps as you can see:

Not quite sure how to use the ‘weld points’ to get the desired effect! (and keep the texture on).

Grateful for your help

Now, this will probably not directly help you but I can’t help mention this anyway just in case because you mentioned that you also tried OBJ.

Did you download these meshes from a website somewhere or did you export them from some kind of software?

Reason I ask: if you did the latter then it might be possble, depending on the software, to use GoZ to send your meshes directly into ZBrush. Many programs support this or can be made to support it in which case you’d be sure of a clean transition.

This would allow you to get items easily into ZBrush, edit them and optionally import your changes right back.

Hi ShellUser

Thanks for the input

I imported them from Character Creator 3 Pipeline (CC3) which does have a Goz function however for some reason my Goz button is greyed out!! Trying to get sorted now.

But in any case when I’ve previously been able to use the Goz function from CC3 to Zbrush the same issue occurs with gaps as soon as I subdivide. I think most people use Goz within CC3 to bring model over, sculpt and then bring it back to CC3 to pose. I just want to pose in CC3 and bring model to Zbrush, use textures from CC3 and not necessarily send back into CC3 - just without gaps in the model!!!
