Hi Mark,

> It could of course be bad modeling on my part.

Doesn't look like it to me - it looks like a problem with Kerkythea's triangulation mechanism.

But yes, exporting triangulated from MoI (or probably Quads & Triangles should be fine) should avoid this problem.

It's pretty difficult to make a triangulator that handles all kinds of complex concave n-gons properly, if the algorithm gets confused, it is easy for it to try and connect up a triangle between 2 points where it shouldn't because it will cause a "leak" outside of the boundary.

just a question
when you enable "Weld Vertice along edges" in Moi : there is no parameter for the strength of this process?
because seems export obj to Zbrush : when you subdivise in Zb : objects seems unweld after a first subdivision!
I have retaken the wire model by Shadows44

and made some sweep between curves for test :)

Hi Pilou - I seem to remember that ZBrush does some kind of automatic unwelding when it imports .obj files in some circumstances - I think it is when the welded points have different vertex normals for the 2 faces that share the point.

Since ZBrush is doing this unwelding on import, you'll need to do the weld operation inside of ZBrush to fix it up - I don't know what is called, look for something like "weld", or "merge vertices", or "glue vertices"...

I will examine that :)
