I’ve been (unsuccessfully) attempting to prepare a .stl file for printing for the past 48 hours or so, and I think the problems is stemming from three target areas which all yield this horrible swiss cheese fungus pattern when I dynamesh the model. Does anybody know a work around for this? Attached are a before (nice, normal looking friendly model) and after (horrible swiss cheese infected death) photo of the model. Any help would be really appreciated.
dynamesh is based on volumes. The areas that are getting the holes are too thin. You can either scale up your model (only works to a point) or increase the distance on the inside of that piece that is getting the holes in it.
Thanks! How do I scale up the model? I’ve never had to deal with these sorts of things before. Do you mean literally use the scale tool to increase the size? How would increasing the internal distance work?
You may be able to enable backface masking (as not to affect the front of the mesh) and then use the inflate brush on the inside of the area where you are getting the swiss cheese effect.
Yes, I mean scale up the model. Dynamesh is volume based as I said. If you increase the scale you will increase the volume.
I am assuming you have polygroups assigned, you can simply grab the inside of that piece and scale it down a bit.
what chrono said would work too.
Dynamesh successful! Thanks everyone! I’m still receiving an error message whenever I try exporting the model to Netfabb for printing though. The error reads “surface is orientable: no”. I think this is due to a multitude of subtools stuck inside the model. Is there a fairly easy way to make the interior of the model solid?

I am brand new to Zbrush and am having the same Swiss cheese problem, but my question is,“Why did the underside of my model move with the top side as I used the clay buildup brush??? Its an additive tool?” I’m confused.
