Thanks Jonah and Michael, I'll give the utility a tryout!

My problem with seperating parts is the polys don't line up at export time - reworking the topology in the poly editor is hella painful especially for curved surfaces.

That's why I'm hoping that MOI will keep track of the polys generated by the mesher and can assign them based on the surface being meshed...

PS - I see the MergeOBJ and SeperateOBJ links lead to the same SeperateOBJ download, is that correct?

That's always a problem. I imagine you could import the whole mesh object into Lightwave, make duplicate objects for as many different "regions" as you need, then delete the polygons from each of those objects until only the desired polygon parts remain...

That normally means that you have 2 surfaces that are sitting next to one another, but are not actually joined to each other.

If you have a situation like that, you should use Edit/Join to glue surfaces like that into an object that has a shared edge, before exporting to polygons - MoI will do extra work when it finds shared edges like that to align the polygons in that case.

If you just have surfaces that are next to each other but not actually joined, MoI doesn't know about the connection in that case and each one gets meshed totally independently and that can cause slightly different mesh structures there.

If that's not what you are running into, could you please post an example file of one of these problem areas? That would help me figure out what is going wrong there.

In general the polygons are supposed to line up if the pieces are joined...

Oops, that was a typo there, thanks for reporting it - fixed now.

Thanks guys, yes, Michael, I've seen you say that before about unjoined surfaces will not have matching edges...

I was working on those nurnies of mines and a couple of pipes had disjoined edges starting at the curves - I thought I had joined them, I tested this now with a quick straight/curved pipe and it appears okay this time...
