Mesh exported from ZBrush is double-sided

[Anonymous]

Hello,

I am trying to retopologize my sculpt made in Zbrush but when I export it as a .obj file into maya the sculpt ends up being double sided which makes retopology impossible.

Also for some reason GoZ for Maya is not installed,

I was wondering if anyone had an advice for this issue?

Do you want to say, that being double-sided the object is irretopolgizable? You can go to the object's shape node in Attribute Editor, section Render Stats and deselect Double Sided anytime.

If you notice that your object is with flipped normals, then go for Modelling>Mesh Display>Reverse. Sometimes, when importing objects from other software, you might wish to Unlock Normals (same menu) before reversing.

As to GoZ, it is not a default Maya plugin, you need to install it yourself.

 This did not work 😞 

I attached a video of what I mean by double sided (the mesh is empty inside?)

All the meshes are empty inside, like baloons. However, did I see the double-walled polygons in your video? Sorry, the captured framerate was too low. Maybe you have exported some model that has "skin" thickness, like an eggshell. Check the Zbrush export options again.

In Maya you can select the object, go to Face selection mode (F11) and double-click one of the faces - entire object is likely to be selected. Now. if you hit Delete, what did change?

Hey! I tried and here is what happens. I also updated GoZ but it doesn't change much. My mesh is also a merge of different meshes so maybe that is where the issue comes from

So, the problem seems solved. Also, you can apply Mesh>Fill Hole to make mesh watertight.
