Modo-to-Zbrush-to-Freeform...SIZE changes?

ZBrush Usage Questions
#1

In my job, I size things in MODO, GoZ them to ZBrush. In ZBrush I have been using whatever it takes to get the files done…Dynamesh, subtools, IMM brushes, etc. NEVER resizing the main sized piece. BUT when I am finished with the job I export out an OBJ to produce a CLY file in Freeform to be sent out to repoduce. My OBJ comes into Freeform at about 10-15% the correct size. IF I go back to my ZBrush file and use GoZ to send over something that is to size in MODO to measure from, my ZBrush file will have changed size…? This has happened twice now, but both times I can at least get something from MODO to size my ZBrush file correctly but it’s very annoying. I keep thinking Dynamesh might be doing something odd to the size…? Maybe I dont understand it enough yet…?

I work with sculptors that are using Modo, Rhino and Freeform…i’m the ZBrush guy so if someone could help, it would make it alot better on me that my workflow doesnt take longer than theirs. Thanks! :slight_smile:

Do a test. Build a 10cm cube in modo. Goz to zbrush. Check tool.export. See wha tour settings are. Snapshot or something it if needed. Work like normal. If your scale gets jacked up these settings were reset to 1,0,0,0 which is where your size difference is coming from.

Another way to work is start with a mesh already at 1,0,0,0 and build or import into that tool.

Zbrush sets a scale it would prefer at import so all of your brushes etc work correctly. It is usually tiny from my experience with zbrush and modo.

Hope that helps.

Yeah, thanks! I will give it a try. I am getting ready to start my next project so I will try this out. COULD be that my settings in MODO are screwing it up? I will run a test and see. It’s just strange that the first 2 OBJs that I have exported to use in Freeform have had something that shrinks down my files. Kinda oddball stuff.

Are you dumping out of z or modo to free form ?

i’m exporting out of ZBrush an OBJ to take to Freeform BUT the change happens in ZBrush before the export. I have only noticed once I have gotten it into Freeform because of the size in there. The 2 times it has happened I have been able to GoZ over one of our Standard Box sizes again that I use and size it up to match it. Both times it seemed to “shrink” the ZTL…something like at least 400%. I am trying to test it on my current project watching to see when it changes or if it does, I sometimes do multiple saves, versions, as I am going.
