Why do some products not work with GoZ?

I have a very specific but very important problem that needs solving. I'm trying to send two clothing items from DAZ Studio to Zbrush through GoZ (which has always worked just fine until recently), and one of them (the padded coat from this set) always tries to return back from Zbrush to Studio as a new object, saying the geometry has changed. I do not change it, only push things around using the Move tool, and I also do it with other dForce clothing items without any issue. I've tried deleting the additional dForce addons and even changed it into a prop; Zbrush always tries sending it back as a brand new object. Does anyone happen to know why this might be happening with this particular clothing item? I need to get this solved for a commission, so any assistance would be appreciated.

    If an item has ngons (a polygon with more than 4 sides), ZB will converts ngons to tris, so the topology of the item will be changed. That was why you got the issue when GoZ back ~~

    The padded coat you named just has ngons (a rare case indeed....). If you export it to OBJ, import OBJ to ZB, ZB will inform you about it. (or you can find ngons in Blender....)

    The solution is simple, you just import it as new object in DS with GoZ. Export the object to OBJ, import OBJ with Morph Loader Pro to create morph properties.

    Thank you for the explanation, that makes a lot of sense except I don't quite understand your solution. Are you saying to return the clothing back to Studio from Zbrush as a new object like it wants to do, then export that newly created static item as an OBJ, and then reimport it into Studio as a morph of the original posable padded coat? I'm not sure what to do next then.

    Yeah, from your OP, you'd like to GoZ back the padded coat from ZBrush as a morph into DS... if I understood correctly. If that was the case, you can just:

    1) Accept Create a new object for the padded coat without SubD (screen shot 1)
    2) Export the object to OBJ format file (screen shot 2)
    3) Import OBJ file with Edit > Figure > Shape > Morph Loader Pro... (screen shot 3)
    4) Dial the morph (screen shot 4)

    Thank you very much. I had some issues though, so I'd like to check a few things. You said to go to Edit > Figure > Shape, Morph Loader Pro, but I actually do not have that option under that path. I had to use Edit > Figure > Morph Loader Pro and then manually change the "Reverse Deformations" from No to Yes. It also broke the attached dForce addon, which isn't important for my particular job here, but was unexpected. If you can, could you share the OBJ export settings for the morph? Do you think I might be missing something, or does that still sound like the proper steps are basically being followed? Thanks again for your help as always.

    The menu path of Morph Loader Pro I told you comes from the latest menu structure of DS 4.24. If you haven't ever done Window > Workspace > Update and Merge Menus in DS 4.24, Morph Loader Pro will be still under Edit > Figure > Morph Loader Pro... so, it's not a big deal as long as you can find it on your side.

    As for dForce dynamic surface add-ons, they're just fitted conformers to the padded coat which are used for keeping the shape of trims when simulating the coat.  Importing morphs in the above way doesn't break the addons. Pls check the settings of exporting to OBJ from the attached screen shot.

    Thank you for the OBJ settings, I will test that as soon as I can. Happy holidays.  :)
