Scale Issues

ZBrush Usage Questions
#1

Hi, I’m sure this problem has come up countless times but I wanted to start a thread and see if anyone knew a solution. I’m using a Zbrush > Maya workflow and everytime I export a subtool to Maya, the scale is really really small. Is there a way to somehow ‘freeze’ the scale attributes so everything exports to Maya at the same scale as it is in the Zbrush viewport? I find that right now I’m having to ramp up the scale in the Zbrush Export dialogue just to get everything to come in nicely together. Thanks :slight_smile:

I’m working with ZB > 3ds max and had the same problem. I’ve found a simple and lazy way to remedy it:


  1. Export your low poly from ZB;
  2. In the other app (here: Maya) size it up to the desired scale and export without any additional changes;
  3. In ZB, import it to the lowest subdiv level - it’ll get enourmous; then you can switch to the highest subdiv.
If you notice that your details are extremely weak (and I’m pretty sure they will be), you can append that sized up model as a subtool to the original one, and just manually size up the original (at highest subdiv; probably a must) to match the screwed up one’s size.

That’s what I did and it worked fine everytime I exported the model to 3ds max since.

I hope this helps. :slight_smile:

Hi there, thanks for the quick reply! Sorry, I should’ve explained it a little better - I meant when I export the mesh out of Zbrush and into Maya, the mesh is tiny in the Maya viewport. Everything is fine in Zbrush, all the subtools are at a perfect scale, but its when I import to Maya that the subtools start coming in at differet kinds of scales :confused:

Yeah, that’s exactly what I understood from it.
This workaround is fine for the target app, while in ZBrush, you don’t really have to care for the size of your model, unless you want to incorporate it into a full scene, also made solely in ZBrush. But then again, even that doesn’t stand much of a problem. :slight_smile:

So, you can resize your model in Maya, have it really big in ZBrush (and don’t care, really), and everytime you export it into Maya, you get it the right size. :smiley:

change the size of your scale at import into Maya. make sure you note this though as you’ll need to do the inverse of the scale during export if you’re going to go back into Zbrush.
