Too bad - it appears to have imported it ok but it looks like Blender is only supporting triangles and quads, not ngons...

It used to be that hardly anything supported ngons. I suppose that's why nobody else has attempted to do an NGon NURBS export before.... Until now. :)

Thanks for testing it with all these different modeling software, that is a big help to know how it is working with different systems!

Import OBJ format with
The Old Amapi 6.1 (became free) perfect! A task!

Anim8Or (some triangles)
Kerkythea (some triangles)
Metasequoia (some triangles)
Wings3D don't Want load !!!
Shade 7.21 don't Want load!!!

It's attached. Here is what it looks like with n-sided polygons and no triangles:

Tricky cutting!

Does Moi will import OBJ ?

A video from Steph who shows that some points are not "merged" but not visible to the eyes :)
So some surfaces are "open" !

Keep the good work :)

I think I have fixed the orientation problem now. Can he please try the attached version and see if it is properly oriented? Thanks!

No, not for V1. I'm not really focusing on having polygon modeling tools in MoI at this point.

Yes, these are the so-called "T-junctions". I plan on fixing these, but that is going to be more complicated, probably not for a few days at least.

That is probably the most complicated part of finishing up this meshing system.

It's ok for Steph for the Normals with C4D :)
He ask to keep possibility of "welding" in option for the toon technic rendering in C4D :)

I shall remake tests with this new file :) (output2)

So with OBJ output2 :)
Same results just better for Wings3D : normals (blue) and some faces curious like in the little base circular round right down )
Silo ok
Amapi 6.1 OK
Bryce 5 OK

Anim8Or (triangles)
Kerkythea (triangles)
Metasequoia (triangles)

Maxwell Studio a lot of triangles !

Shade 7.21 do not load (Buffer overun)

Yes, there will definitely be an option for doing it or not, so don't worry, his toon rendering will be safe... :)

It may default to on, and he will just have to uncheck it for doing toon renderings.


I'm currently working on a way to have the density increase and decrease much more gradually as you move the slider, this should help reduce the current problem of trying to get a little bit more polygons in one area and having other places double in density and become too heavy.

Very nice!
But yes as you said when you import this into Rhino it tends to get mesd up and triangulate:-(
Any way to avoid this so that you have quads in Rhino?

No, not really. Trimmed areas just don't naturally generate minimal quads, they more naturally generate minimal n-sided polygons...

Some examples in Modo 202
Seems there are still some problems importing the geometry there...

More than 16000 vertices merged when I used the "merge" command !

Render in Modo 202.
Not bad at all, but some missing geometry and artefacts...

I used the new output file

Hmmm, that is disappointing. I sort of assumed that Modo would be more robust in this area, as best I can tell right now those seem to be bugs in Modo's handling of ngons.

I closely examined the area where you've got a hole near the bottom in your test using the new output, and I just can't see anything wrong with the polygon structure there, it's a pretty simple 5-sided ngon..

But we'll see - maybe I'm putting out duplicate points or something that Modo doesn't like. (Edit: after checking, I can't find anything wrong there).

I've attached a file here that contains just that single 5-sided ngon. Can you please test this with modo and see if it will read it or not?
