Problem with cloth imported from Marvelous Designer.

ZBrush Usage Questions
#1

Hi, I’m new to Zbrush and MD.

I made a simple robe in MD for learning purposes. I wanted to add detail to it in ZBrush, so I imported the .obj file, applied ZRemesher and then QMesh action to add thickness to my robes. Everything looked fine, but when i tried to smooth the surface, i got this:

The first stroke of the smooth brush only pushes the external side of the robe, and the inner side remains unchanged. Of course, if i then use smooth on the exposed inner side, it gets smoothed, but as you can imagine, this lead to a mess in the geometry very quickly.:roll_eyes:

PS: I also tried to use Store Morph target + Inflate to add thickness, but still i got the same error when i use smooth :s

Please, i need help with this. Thank you very much and sorry for my english.ouch.png

It would probably be easier to do most sculpting before you add thickness to the mesh.

You can also derive a mesh with thickness by masking the mesh and using themesh extract function.

When working on a mesh with two surfaces close together, it is often useful to turn on Backface Masking in the Brush > automasking palette for the brush being used. This will let you sculpt on one side without affecting the other. If the two surfaces are separate polygroups, you can also hide or mask the interior surface quickly with shortcuts.

I turned BackfaceMask on, but in this case, it didn’t work. I’ll do as you say, adding thickness only in the last stage of the sculpting process.

Extract operation works well, i just wanted to try a different approach by importing cloth from MD.

Thank you for your reply, Spyndel.

If the import from MD is a 2d mesh without any thickness, there’s no reason you cant extract a thickened mesh from it. You’d simply mask the entire mesh prior to extract, rather than just a portion. If you extract with a negative thickness setting and with “double” switched off, it will leave the exterior surface unchanged, and extrude towards the interior, not really much different than extruding with Zmodeler, except that it leaves the original unchanged and instead creates a new subtool.

Remember, If the interior surface is a separate polygroup, you can hide it by shift-ctrl clicking on it once or twice depending on context. This is a 100% foolproof way to keep from affecting anything but the exterior surface.
