Hi Raven, that's just it though - sub-d modeling programs are entirely purpose built around manipulating quad control cages.

So they're a better fitting tool for working on that kind of data.

It's best to do the sub-d modeling inside a sub-d modeling tool and then you can import it into MOI using SubD > Create > "From file" instead of trying to use MOI as a sub-d modeling tool itself which it isn't.

it's more funny to make directly subdivision in Moi!
With only 4 functions!
(And of course any native Moi functions! (Like Extrude...in some conditions :)

thx Max Smirnov!

Found what I needed - it's just sSplit :) Makes things way easier than projecting curves & then trimming

Boy some folks here have way more brains than I'll ever use - there are some great scripts & commands I never knew existed....

For 5 (maybe 6) and 3 ngones, you can often just apply a subdivision level to your 3D poly model before saving; you will get a full quad model.
It also works with any type of ngones, but the topo result might look unpleasant.

Chasing ngones is a good thing, but at the end, it's the number of edges connecting to a single points that will create "ugly" result (bad topology flow), and it's often way more tedious to fix.
If it's just to satisfy some loader restriction, pre-subdividing the mesh can be enough.

---

When you say 'apply a subdivision level' do you mean use something like sSplit?

---

No sSPlit (in Moi3D) is used for add Lines cut for Divide a solid ( or add faces ) for facilitate the Subdivision!

_SubdivBeta9 makes the Subdivision of the solid(s) itself! (round the volume(s))

Here like 100 levels of Subdivision! ;) in Moi : in another prog that will be 0 to 7 because numbers of facetts x 4 at each level! ;)

In Hexagon 2 : 0 to 7... Level 3 is yet a cool sphere ! :) And want not explode my Hard Memory!



In Moi3D It's like a game because you must always find some tricks for have a solid(s) without internal faces !
And better to have "quad" faces!

https://moiscript.weebly.com/la-subdivision.html

SSplit only one edge


SSplit on faces! (special here because start is not a quad so SPlit ones Top & Bottom !


SBridge + _SubdivBeta9 at the end
S

SSize (works with Control Points) + _SubdivBeta9 at the end


Then the Free Vizcom for some cool rendering! ;)

ect...

Ok so Subdiv does actually divide into smaller polys - it just doesn't show them?

I notice the beta6 has a High Quality mode but the beta9 doesn't seem to....

---

Btw - nice work Frenchy :)

---

I wouldn't say that: I believe subdiv convert the solid(s) in surfaces Nurbs! ;) like patches....
And you see them !

Can be less or more numerous (patches) depending of the Original OBJ and method used!

Here the Native SubD / Create from file


Moi is not a Poly modeler!
We can simulate Subdivision in it! ;)
Thx Max Smirnov!
Compare to this ligh one! :)
_Import OBJ

Hi Raven,

re:

No, the Subdiv plug-in works somewhat differently than applying subdivision in a poly modeling program.

In a poly modeling program you can apply subd smoothing which generates a denser mesh. There's a good overview here:

For SubD to NURBS surface conversion it's a little different. It isn't making polygon output in steps, it's trying to make a smooth "limit surface" result.

Hi Pilou,

re:

It looks like you're importing a triangulated or high density mesh there.

To be clear, that's not what you should be doing. You should have the sub-d control cage in the .obj file you import, not a high density already subdivided or triangulated render mesh.

- Michael

---

Yes i can have different options! :) (free Hexagon 2)



And seems that your Create from file is very similar than the CatMull Clark ? (first on the left)
On the left i took Doo Sabin Level 2 (before Import inside moi)

I obtain the same result than Catmull Clark if I import the OBJ at level 0 so straight lines!
It's Moi that makes the subdivision (same result than Catmull Clark! :)
If I send a not subdivised file i have the result on the right! So Cool!

Hello 777RAVEN777,

Sorry I kinda miss the fact you are creating your "poly" model in MoI.
I was referring to poly modelling software, where you can simply add a level of subdivision to an arbitrary surface and thus create a full quad mesh.
It indeed does add complexity to the model, but it's a quick way to generate quad only topology and thus bypass some mesh loader limitation that doesn't handle ngones.

Hi Pilou,

Right, that's how you want to do it.

The other result you're showing like this:


is because you're converting into smaller triangles and then trying to process that triangulated mesh as a sub-d control cage. That will make an extremely dense surface and also introduce a lot of bumpy artifacts so it's not a productive option.

Yes...was to see what it would be like the result of take a subdivided objet...
so not useful except if you want have some base design for some cool graphic extrudes! ;)

Really dude stop posting 40 AI images in every thread you take part off, we get you excitement, but this is just stupid now ... as annoying as vegan activist !

---

Why not use new paradigms ?

---

At this point it's more good manners or forum etiquette.
Beside it's doesn't add anything to the topic right ? It's just random stuff.

You already take over the MoI discord, WIP : Pilou AI, Finished Work : Pilou AI, Pilou-gallery : Pilou AI, ressources : Pilou AI ... don't you think you push it a tad too far ?

I know you as active member for many softwares, and I know you are an helpful and chill person, bit really that AI spams is just out of control.

---

I find his work pretty inspiring - I'm in awe of some of the examples folks have posted in various threads here - and to think it comes (mostly) from this genius bit of software we're all using :)

---

For my part, I've decided not to present any more of my work on the forum, and not to make any more comments after this one. I don't want to be phagocyted anymore.

I think I'll also delete all the images I've posted on the forum.

I'd also like to ask Mr P. to remove my “FrenchStrings.txt” file from his blog.
