Dynamesh kinda freaks out

[system]

Hi,

recently i had a lot of problems when i started to work longer with dynamesh on. Mostly after changing the resolution, my whole model changes its surface into some… hard to describe ****ed up state. see it here:

the head seems to be not affected by this, he is a seperate piece. First thing that came across my mind was that zbrush somehow treats this like it had an outside and an inside and dynamesh got confused because it is so thin. but anyway how do i fix it? had this with 4-5 other models too and its annoying

is your entire mesh visible inside of tool.preview? dynamesh is very reliant on mesh scale.

if you mean all parts in its whole, no, the face is somehow missing. body is displayed. if you mean based on its size no, its quite zoomed in and not visible in full

im very glad that at least one person is trying to help me, but i still encounter this problem. and now if i start with the dynamesh128 preset sphere and start modeling a head out of it thats even smaller than the sphere was the same stuff is happening. pls help me
