@Gordon Robb, @Justo: I apologize for the extremely late reply on this; Gordon you are correct the error appears to be related to the scale of the mesh. If the model is too tiny when it attempts to calculate the resolution to generate close to the desired Polycount it will throw that error (basically telling you that part of the mesh will result in no vertices at that resolution.)
I will look into seeing if I can remove this from happening 
-Joseph
Yes Joseph, but I’ve had it happen with tools that normal dynamesh will work with, but just not enough resolution. I’ve also found that it sometimes doesn’t work with a or unitive, but will once it’s been dynameshed. Also, it gives you the error, and then goes ahead and creates a really low res tool, rather than stopping.
Thanks for sharing this awesome plugin.
I really do like the idea of the polycount slider a lot.
But when I add the Dynamesh button and the resolution slider to my custom interface ZBrush hangs and has to be closed by force. Tried this several times and each time I get the same result.
I use Win7Pro with the latest 4.7
@Erik Heyninck: You should be able to drag these into a custom UI and still have them work (I can not get the buttons to cause a crash on any of my machines.) Do you have an overabundance of Zplugin buttons linked to your UI? If you load the default UI and create a fresh custom UI with only those two options does it still crash?

I love this plug in and have used it for a good while. Thanks so much for sharing it with us Joseph!
I’m having a problem on a 3D print I’m preparing. I have a project for a character made of several subtools with a total of 13 million points. However when I start to combine these subtools and get down to one I can’t seem to get higher than 3 million points. I get this result regardless of settings in Dynamesh Master. I also get the same results in the standard Dynamesh plugin.
Changing the physical size of the tool seems to have no effect. I can start the slider at 128, hit Dynamesh and get a low rez result as expected. However, as I move up in resolution I hit right around 2.97 million points and that’s it.
It’s almost as if there is a hard limit setting for Dynamesh but I don’t know of any such thing and Dynamesh Master appears to allow for much higher resolutions.
The only setting that appears to allow for more points is to leave Group turned on, but that leaves me with intersecting forms within the single subtool which I think will not allow for printing.
I seem to remember not having this issue before so I’m sure it’s something simple that I’m just not realizing right now 
Any ideas? Thanks!
@HeavyTheory: I have encountered the max resolution item as well; most of the time it is related to the model being ‘long and skinny’ (example: gun silencers, missiles, telephone poles etc…)
To start check the Size of your model in [Tool:Geometry:Size]. The DynaMesh process usually generates the maximum amount of resolution in 4R7 P3 with a XYZ Size anywhere from 2.0 - 2.5 and resolution set to 4096 (If you DynaMesh a default cube you end up with ~10 mil.) After the size goes larger then that you will probably not see an increase in DynaMesh resolution. (The DynaMesh Master plugin auto scale function was created to primarily work with small sized objects.)
If you hit the DynaMesh maximum you can always divide the mesh and then project. So you can ‘Merge Visible’ on the model to create a single Subtool then append that to your scene. Then create the DynaMeshed version of the model that is giving you the 2.97Mil point count. From here divide the model up as you would normally (This will get you above 11 mil no problem.) With the DynaMeshed version selected and the Merged tool visible; change your project all setting Dist to .1 [Tool:SubTool:Project:Dist .1] then do a ‘Project All’ [Tool:SubTool:Project:ProjectAll]
This should project the details back from your 11mil model to the Watertight DynaMeshed version. Let me know if that helps at all

Hey Piggyson, just wanted to say that you’re awesome and thanks for sharing this. The problem with the scale of the mesh can be a bit tedious, but it’s a minor thing when compared to such an awesome thing. The way I solve it is to export as obj the mesh, import, and then dynamesh it (for some reason there’s not a problem anymore if I do that).
@Piggyson Hey Joseph. Thanks so much for the quick response. I looked at my physical size and I was all the way up at 30 for some reason. I brought it down to 2 (If I was understanding you correctly that it’s the best range for Dynamesh) and tried again at 4096 and then in Dynamesh Master at around 6 million, but both options just barely got me to 3.1 million. It still seems there is something going on that’s causing a hard limit but I’m not sure at this point. Just so I’m not crazy - there is no way a setting in Zbrush could be causing this is there? Seems like it would be a built in limitation. It’s still probably something I’m missing. I’m including a grab to show the proportions of this tool. I have this kid laying on his back. Could it be something about his orientation?
However your suggestion about going with the low rez Dynamesh, subdividing, and projecting is going to most likely get me to the finish on this one and I greatly appreciate it. Thanks so much!
P.S. I live in Charlotte. If you get a chance I’d love to talk to you offline about meeting up for some paid Zbrush training/consulting if that wouldn’t be a conflict for you. Thanks man.
@Justo I tried your suggestion of exporting as an OBJ and importing again but it still yields the same low rez results for me. I’m glad it works for you though:D
Great post! like it.
This is very cool 
. Well done. 
Big fan of this script. Would love a zremesher equivalent 
Why I can’t get meshes higher than 4.125 millions polys with this plugin?

This plug is great! Thankyou very much indeed.
There seems to be an annoying change of behaviour. I used to be able to press Scale up Visible, and it would increase the size of the subtool selected. Now it scales up all the subtools which have the eye on. This means that the subtool I have selected (whcih never has the eye on) is the only one that does not scale up.
What gives? I haven’t chaned anythign.
@Gordon Robb: What you are describing is how it has always functioned You can scale the selected subtool, scale all the subtools, or finally scale the visible ones (with ‘eyeball icon’ on.) The plugin has always required the ‘eyeball icon’ to be on in order for ZBrush to process the subtool as ‘visible.’ If the selected subtool has the ‘eyeball’ icon on then it should process the selected subtool.
Eventually I need to rewrite this plugin as the Dynamesh process in relation to scale has changed slightly since the 3+ years when I released it (also my ZScripting was a little bit of a mess back then too )
-Joseph
@Piggyson - Damnit. I’m an idiot. I was all indignant ready to take a screenshot of my interface and tell you you were wrong, when I see I’ve been pressing the wrong button :). I used to hit Scale up, but I’ve been hitting Scale up Visible. Doh!
Thanks for pointing out my ineptitude, and helping me
Honestly, I don’t know how I manage to get dressed in the morning
Hey all, just wondering if this should work in 4r7? have placed most recent version in zplugs folder but no joy unfortunately.
Yes, I can confirm it does work with 4R7. I had no problems installing.
Thx sooo much for every scripts u make and made to make our life much easier
