Artifacts when Remesh a cylinder

#1

I’m new to ZBrush … While following some tutorial i’m trying to remesh a cylinder to remove the top cap polar vertex, but i get his weird mesh instead of smooth mesh, can anyone plz explain this
effect for me?

Here’s the process to reproduce this image :
1- remove the bottom cap.
2- Tools > Remesh
- Res = 64
- Polish = 50
- PolyGrp = on

Thanks.

There are lots of ways to do it. For instance, I just dynameshed it at 128 resolution with Blur at 0, then ran ZRemesher (at Half, Adaptive
Off) a few times.

when you Tools > Remesh
go to your new tool in subtool and select it then press
tool>subtool>project >project all

you may need to mess with some sliders like >dist
