HELP! - DYNAMESH problem - HOLES in my model need closing - my MODEL inside

ZBrush Usage Questions
#1

Hi I hope someone can help me. I am working on a project that will be printed and I need to cut the head off my zbrush model so its printed separately. My problem is that after slicing off the head, the head and the body are not solid objects. They have open holes as you can see in the enclosed pic. I want to fill the holes to make the subtools solid.

I took my model into dynamesh, froze the subd’s pressed group then used the slice brush to cut the head off my model. I then exited dynamesh. Everything seems to work and I get my new subtools of the head and body. Only problem is they are not closed. Also worth noting, on this model I have 6 sub’ds. When I successfully cut off the head the head lost all its sub d’s and I could no longer step down to work on lower res sub d’s. Anyone know why that happened and how I can get around that problem as well?
I watched the sample videos and read the tutorial on dynamesh and slicing and I assumed I am doing it right but obviously I am not.

I thought I found the answer to my problem when I chose close holes under geometry and it does work but you cant have any subd’s. So that option wont work if you already have a model with multiple sub d’s. Since all the sud d’s were deleted from my head after slicing it filled the bottom hole, but when I tried it on the body it says it cant do it because of the multiple sub d’s.

Can someone please advise me on the proper way to close these holes and the right process to cut pieces off a model such as hands, heads, feet so I can make new separate fully closed subtools of them while retaining my subd history?

Thank you so much for any help. :slight_smile:

well for one… make sure double sided is turned on in display properties…

and to to fix it… just drag the mesh over untill it looks closed with the move topological tool and do the normal CTRL drag outside the mesh to close it up :slight_smile:

hope that works for you if you have errors still with small holes… use the inflate brush on it a bit and CTRL drag then smooth it out

good luck

Also, if you slice in Dynamesh with ‘group’ activated, it will make each part a sepereate part, with no holes.

Altermind thanks for your help? - I chose double sided and that part looks better. :slight_smile: Are you talking about using move topological in Dynamesh mode? I havent tried that but will and see how it works.

My preference though is to get it capped off cleanly from my cut outside of dynamesh. Is there any way to do this outside of Dynamesh that you guys know of? I just want to fill that hole in the neck and head so I can have fully watertight separate subtools.

Gordon - I did have group selected when I cut the head off in Dynamesh but the problem was the head and the torso and head weren’t filled, the holes were still there. I’m stumped.

Now if I have no subdivisions on my model I found that I can simply choose CLOSE HOLES under geometry pallette and it does exactly what I want but when I try to use it on my model with multiple subd’s it tells me - THIS FUNCTION CANNOT BE APPLIED TO A MESH WITH MULTIPLE SUBDIVISION LEVELS.

Any thoughts?

Hi there,
you could try the new “Freeze Subdivision Levels” feature and then the
“Close Holes” ,maybe,don’t know for sure,but worth a try.

jmeyer - YOU ARE A GENIUS!!! That worked perfectly! I dont know why I didnt think of that. :slight_smile: Thanks so much this has really helped me out alot!
