I apologize if this problem has been posted before but I couldn’t find anything similar. Today I came across Dynamesh system in Zbrush and I tried to apply to a cloth that I created. Now the issue is that after I apply the Dynamesh on the cloth that looks like this:
it transforms it into something like this:
.
I don’t want to fill up the wholes. Is there anything I can do about it?
I appreciate you time and help.
Thank you.
Hi there,
I was a little surprised when I first encountered this too: Dynamesh requires a closed, watertight mesh. If it is an open mesh, like a zero-thickness cloth, it closes it.
You can avoid the problem by adding thickness to the mesh, like so:
In Morph Target click “Store MT” then press shift-S to put a snapshot of your mesh on the canvas.
Go to Deformations and resize the mesh by as much as you want it to be thick (using inflate or size, whichever works best for your mesh) using the snapshot as a guide.
Next go back to Morph Target and click “CreateDiff Mesh”. This will create a new mesh with thickness which is the difference between the morph target and your resized mesh.
Press ctrl-N to clear the snapshot from the canvas.
Go up to tools and select your new mesh. If it looks all inside-out, go to Display and click “Flip” to flip the normals.
One tip:
You need to give it sufficient thickness, otherwise dynamesh will mess up and you’ll get a bunch of “moth-eaten” holes in the mesh. And likewise when you are working with it, you need to make sure you maintain sufficient thickness to avoid the same problem when you remesh. If you do get holes, you can use the inflate brush and then remesh to fill them in.
Due to this, this method is not great for making thin cloth…
An alternative is to let dynamesh fill up the holes, work on the closed version of the cloth, then use “Create Shell” in Geometry, underneath Dynamesh, to make a shell with a certain thickness (see ZClassroom tuts) – it’s fast, but you can end up with big polygon counts and of course you get dynamesh topology.
Or use ZSphere retopology to recreate the zero-thickness mesh around the closed dynamesh – it’s slow and often frustrating, but you can get an efficient mesh with good topology.
I completely agree with teeg000 , however i do have an easier solution … convert that sucker into an OBJ and export it to 3ds max (or any other software you prefer) give it a shell modifier, collapse it and pop it back to zbrush. the Dyna should work just fine.
Good tips from teeg000… but there is an even easier way.
First I would add edgeloops using Geometry > GroupsLoops with a low GPolish (I turn off triangles)
Next, use Subtool > Extract
Clicking the extract button will give you a preview. You can adjust the thickness with the slider.
When you are happy with it, click the Accept button. This will give you a closed mesh with thickness.
Then just create your dynamesh.
Hy guys, I want to thank you for your replies. teeg000 I was thinking exactly the same way as you, I did tried before I posted but the truth is I didn’t know how to fix the holes in the mesh after adding the Dynamesh. I’m grateful for your help so I know now how I can fill the mole wholes.
Thor I did tried first your way but it gave me so many requests, that the mesh to be in a low res and not to have layers and all that so when I gave a try to renthehungry method and that work very quick.
Thanks everyone for help. I’m sure every way has it’s good’s and bad’s part but will be used in an appropriate circumstances.
Best regards,

Hahaha I win !!! lol kidding …this is why I love this forum … I have just learnt 2 new tips within Zbrush !!!
