Added this extra ZBrush tip to my initial post:

I assign differently colored styles to key surfaces in MoI, and import in ZBrush using the option to import Obj materials as polygroups. Then I use those polygroups as ZRemesher guides by activating the KeepGroups option.

very useful feature! just can't find moi.ini
where it is?
PS: I found 4 files in different locations. which one should I choose? Application data or AppData/Roaming?

Hi gmlr,

Try C:\Users\<usr name>\AppData\Roaming\Moi

Best,

thank you!

Non-centric vs centric ? Does it make any difference when exporting STL for 3D printing?

Hi Ed,

Good question. I don't know if the two triangulation methods only divide quads in a different triangular way (then there would be no or almost no visual difference in the polygon structure), or if they each result in a visibly different triangular polygon structure.

I hand over the microphone to Michael for this. :)

Hi Ed, centroid triangulation shouldn't make any difference for 3D printing - ZBrush seems to be sensitive to the triangle structure.

But one thing that I think is good for both ZBrush and STL export is to use the "Divide larger than" option which will chop up anything larger than the distance you put in there. It can be good for both of these exports to try and avoid having triangles span a large distance across the object, it tends to make the triangulation more apparent in the final result. ZBrush needs a finer level of dicing though.

@Metin, this setting won't change how quads are triangulated, just n-gons which you'll get at trimming boundaries.

Hi glmr,

There's a button that will tell you where it is and also open it up for you under Options > General > "Edit .ini file" :

Thanks for the additional info, Michael. Only Ngons are triangulated of course, not quads, my mistake. And I tend to forget the presence of the button shortcut to the Moi.ini file, thanks for that reminder too.
