Hi! my student has grid like artefacts after using the smooth and standard brushes in a lower subdivision, then going back to the higher subdivs. It progresses to vertex disorder and sharp edges from vertices jumping to far out positions.
The Ztool has multiple layers, and some polypaint. What could be the issue?
Perhaps a re-install? or making a fresh copy of the model and reconstructing the layers via projection?


Zbrush version 2021
Thanks!
