Remesh Jaggy Help

ZBrush Usage Questions
#1

Hi guys, sorry if this has been addressed before, but I was unable to find a solution thus far. I am remeshing a few hard surface pieces in ZBrush, but when I remesh I can get the shape very close, except that the edges tend to form a good amount of small jaggies upon projecting.

My steps thus far:
Original piece solo’d and divided up to about 900k~ polys
Remesh piece then visible at over 1 million polys,
Project all - to get the details from the original mesh to the Remeshed mesh - This is where the Jaggies pop in, and I can’t seem to find the right settings, and I believe that since the remesh poly count is higher I should be in the clear. Can anyone lend any insight please? :slight_smile: Thanks a ton!!

The problem with remesh for hard surface shapes is that it doesn’t give you clean edgeloops that follow the curves of the surface, instead it’s more or less a uniform grid of quads that gets projected onto it. So you’ll run into less than ideal bevels like this.

You can try increasing the resolution to see if it helps any. 1 million faces can seem like a lot, but a lot of it is being spent on those planar areas. The problem there is that if you go too high, you could make your system unstable when you go to project.

Dynamesh is a similar option, but still different enough with it’s options that it could be worth a try. QRemesher could be more helpful with the right curves guiding it. Manual retopology with zspheres or the retopology brush would give the cleanest results, though would require the most manual input. You could also try getting the different sides of the model into different smoothing groups (the slice curve brush might help speed that up, depending on what the rest of the model is like), and then try using group loops to polish the areas in between.

Thanks, Cryrid! I’ll try out the Dyna and QRemesher before I go and painstakingly do it by hand. Haven’t tried ZSpheres yet, but will look into that also. Otherwise it’s back to topogun for me!

Thanks so much for the help!! :slight_smile:
