zbrush3 problem

Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

what was the file extension for the file from maya?

Z only accepts certain model types and I'm not 100% sure it accepts ma or mb files...

ahh, I think, but I might be wrong, Z does flip axes you can see it when you make a texture, though it does go back

But yeah, why just sculpt one side, if you going into Z you might as well do the whole lot.

Also get the upgrade to 3.1, its free, and is a lot more stable than 3.0.

Can't you just unflip in Z-brush??? or maybe do a -1 scaleX before exporting...

I open it with Zbrush 3.1 and i choose " symmetrical triangles only" then when i hit "X" for sculpting everything is allright. But if you have problem with the center go back to maya center the pivot, delete history and then try again. If not working again go in Zbrush
-> deformation - > smartResym, Resym

Try this options

And one huge mistake that i did before. Don't use crappy mesh and import it to Zbrush to fix it .... It will be pain in the ass and if you want to go back in Maya it will be failure for rendering the normal or displacement map. Try to make as good and clean low poly topology in Maya then go in Zbrush to sculpt only the details. Don't be lazy...!
