Zsketch on Non Zsphere Model

I was wondering if it was possible to the sketch on a model that didn’t start out created with zspheres. Basically what I’m trying to do is reinforce delicate parts on a 3-D scan so they can be 3-D printed as well as plugging up holes. Before this I would just append some geometry sculpted it the way I wanted it, merged and then dynameshed. I also started using oculus medium to create this virtual ”epoxy” filler geo over the scan then brought both meshes into zbrush. However if there’s someway that I could just get the scan to be seen as is a zsphere model I could skip that step all together and just use zsketch.

Welcome @Montrose_Edmonds

You don’t have to sketch on ZSpheres to use ZSketch. Just load your scan, append a ZSphere, select the ZSphere and start drawing on your scan. Basically like retopology in ZBrush. The problem is though that you’re still going to have to make a Unified Skin of the ZSketch, then append and merge that to your scan. So you’re back to square one with when you “append some geometry sculpted it the way I wanted it, merged and then dynameshed.” Where this would help though is that the Unified Skin would already be molded to your scan.

A couple alternate suggestions.

  1. Remember that Dynamesh will close holes by default. This works best with relatively minor holes…large sections of open mesh will likely produce deformities.

  2. Mesh extracts are a very fast way to “glop” some new clay onto a surface or into a crevice, and work with the standard brushes you’re used to, as opposed to Zsketch, which has a completely different toolset. It’s as fast as simply painting a quick mask at the target area.

  • The resulting creasing can be removed in the Tool> Geoemtry> Crease menu, to remove the creasing around the edges for a softer “blob”. Or you can quickly dynamesh it to scramble the topology and make it more sculpt-able.
