Strange extra geometry?

ZBrush Usage Questions
#1

Hi All. Using ZBr3.5r3 on PC, XP64, 8 gigs RAM.

At some point I had tried to retopologize a part of this tool. I abandoned the attempt and continued to work with it as is. However, ever since then when I start sculpting in an area and then smooth I get these strange artifacts poking through the mesh – see attached pic.
They aren’t part of the actual tool’s mesh as far as I can tell.

they are only visible on higher subdiv levels, and I can’t figure out what they are or how to get rid of them. I associate them with the retopologizing also because they seem to have something of that ZSphere two tone coloring. Anybody know what this stuff is and how to get rid of it?

I’m having a similar issue that was caused from using a claytubes brush that was too large for the area I was sculpting. For some reason, z-brush won’t let me use ctrl-z in this situation, so I could also use a solution.

Does no one have any ideas about what causes this and how to fix?

they look like polypainted materials, choose the flat material with mrgb selected and fill, see if that helps.
also if not, post a pic with the wireframe showing

Yes, I agree post wire frame.
Maybe you highrezed an area by accident. or your retopo is laying on top of the old topo???
Try all things these guys are mentioning.

“Reproject higher subD levels” button solves a lot of problems for me. Will work faster than retopo and if your topo is pretty good just in the wrong place this will be more efficient . read the Docs on it please.

Also if you duplicate a new lorez mesh, delete higher levels. check for errors in maya, subdivide back up in zbrush. Project all, Morph target if most of this looks ok, soften out all bad projections and morph brush all softened areas up to the twisted parts.

Maybe try exporting this mesh separately, re-import into new scene
try exporting lorez mesh also, use zsphere retopo method, read docs! just get zsphere, append highrez mesh, append lowrez mesh, no retopo this time. just adjust projection strength. preview adaptive mesh , make new mesh.

if all else fails use zproject brush, save morph targets to repair sharding, and stay away from the edge

There’s really a lot of different good ways of fixing your meshes in the new zbrush versions.

Thanks, guys. Finally had time to return to this project and the flat material fill seems to have fixed the issue. All help most appreciated.

Excelsior!
