[Beginner] How to solve "strange polygons"

ZBrush Usage Questions
#1

Hello! My name is Vittorio and I write from Roma, Italy.

I hope that this is the right place to post a basic help request.

I am new to zbrush and I am following many interesting tutorials that I could find on this and other internet sites.
I am experimenting with some models and brushes and I notice that more than once I get a “strange polygonal situation” like the one that you can see in this picture:

I am working at a relatively low level of subdivision and I don’t want to go up (it usually won’t fix the problem). If I try to fix this the polygons moving them with the move brush or “adding” material with the one of the clay brushes or the standard brush I usually get a mess with my mesh.
This is how the polyframe looks:

I tried with the Dynamesh and a resolution of 128 and 256 but it doesn’t seem to work. I also tried to manually move this polys with the move brush without success.

I usually face this problem when I work with a low resolution mesh and/or when I use the transpose (for example to pose my model after I finished working with it using symmetry).

What I could to to partially solve this situation was to use the smooth brush to soften the edges and recover the mesh, but this approach usually work just for “easy” situations.

I am wondering what an expert user would do in such a situation. Unfortunately I noticed the problem (and it is not the first time) after some time, so I can’t go back in time with the history.

Thanks for your help!

your volume is too small right there. Increase the volume using the inflate brush (really push it out) and then re-dynamesh. Then move/sculpt it back in place once you get a clean mesh.

Thanks. I was able to use the inflate brush and get a solution.

Another problem that I am facing in some parts is that, at one particular point, the mesh seems to have some missing polygons here and there. I tried to use a zsphere approach using the rigging and topology command and I was able to generate a new “skin” that I projected on the original geometry. This approach is a little bit time consuming and maybe you can suggest me a better solution.

I also tried to inflate and to move the geometry but I could not success.
