Changing Importing Preferences after the fact.

I think I made a huge mistake, and was wondering if there is a way to fix my error. So, initially when I started working on my first character that was originally created in Maya I imported the mesh but never changed my preferences in Zbrush on how the model was imported. I.E The mesh is coming in correctly in the Y axis. However, is rotated 180 degrees in the wrong direction. ( His back is facing forwards. ) Now when I am exporting out all of my displacement / Bump maps, I think this is why I am having an alignment issues, when applying my maps back in Maya.

The reason I think I am having a alignment issues is when I look at my model in Zbrush I have scars and features that are on the right side of the face. But when I apply my maps in Maya the scars and features are now on the Left side of the face. I have tried to flip my maps both in Zbrush and in Photoshop horizontally, but then I know that they do not align up with my UV’s

So, does anybody know how I might be able to change the direction of my model after the fact, now that it’s a Zbrush tool? I have done way to much work to go back to the begging and start all over.

Hi, rather than mirroring the maps, can you not mirror the whole object you export to Maya, say within Maya? You could mirror in zbrush but it requires you have no subd levels so you would have to reconstruct, but it should work in Maya on your exported model. I would avoid doing the mirror until the very end, so you don’t have to import a new model and try and get all the high freq details to sit right.

Rhumba:

Thanks for the quick response. However, I am not sure that I understand what you are saying. (can you not mirror the whole object you export to Maya, say within Maya? ) What do you mean Mirror? Do you mean duplicate the model however, use -1 in the x axis to make a mirror?

Thanks Again.

The simplest way is to change the export options in ZBrush. Go to Preferences:Importexport and set them so that your model exports correctly. If you don’t save the UI configuration then the changes will not be permanent.

EDIT: It will probably still be necessary to flip your texture/ disp maps.
