GoZ <> Maya problem

ZBrush Usage Questions
#1

Dear PIXO’s

I need your help with this very annoying problem. I have build a character in Maya. To be honest, it carries a lot of triangle topology. Let’s say 1/8 of the model. It’s my first so that’s why I quess.

Now here’s the thing. I use GoZ to bring it into Zbrush(4) and refine the model. When I do so, the model looks quite the same as it did in Maya. I refine the model and bring it back into Maya(again using GoZ). But when I do, Zbrush seems to be doing something to my character’s topology in such a way that I lose a lot of detailing. Deeper and finer shapes as I made in Zbrush are gone and my model seems to be smoothed out, as if you subdivide it in Zbrush to a very high level. Which I did not do. I bring it up to level 3 or something.

What is strange is that when I do not subdivide it in Zbrush and make some big adjustments, my model is not affected in the bad way when I reload it in Maya.

It’s causing me a lot of headache and I am afraid I will need to rebuild my whole model due to the triangle topology which is maybe causing this problem.

So my question:

  1. Is the problem caused by the triangle topology? Or does it have to do with a setting in Zbrush?

I appreciate the help in a great way and thank in advance for your help!

If I cant fix the problem I am thinking about rebuilding it totally in Zbrush and then bring it back to maya to animate it.

My second question:

  1. Is that doable?

Thanks a lot for the help!

Dear Pixo’s,

I just came to discover that the problem I have has nothing to do with GoZ not working or causing the problem.

I discovered that it is the subdeviding that is causing the problem.

When I GoZ the Maya model and raise the SubD level it affects my lowest polymodel stage irreversableally.

Now my question is if there is a way in which I can raise the SubD level and that that process does not affect my lowest polymodel.

Even when I do nothing to the model and only raise the SubD level and GoZ it over to Maya it smoothes out my model.

Very annoying and it would help me a great deal if someone has some suggestions,

Thanks a lot!!
