Hi Max,

can you help in install your subdivid beta9.

I have copied all the files (new importobj also) in the commands folder, but nothing happened.

Thank you for your help and incredible work in the created of subdivide surfacece.

Hi gara,

Did you install a shortcut key in MoI Options icon?
For example: Select Options / Shortcut keys,
and add a new entry of your choice, such as Alt+F in first column, then _Subdiv_beta9 in the next column.

or for example, Alt+/ _Subdiv_beta9

The prefix _ must match the prefix of the _Subdiv_beta9.htm and .js files. _ is not required, but its presence or absence must match.

Then close and open MoI again, load a solid polygon, such as Box, select it, and type in the shortcut key combo,
for example hold down the Alt key and type F.

(I now use Max's custom ui for Ext.scripts, instead of shortcut keys, and also use _ prefix for the non-basic MoI scripts)
Either method, or both methods may be used.

Thanks Brian,

now it works!

I had miss the step to close and open again MOI

I have imported a simple object like a cube, and the obj importer works, but as I apply the subdivision and change the value with the slider appear an error, and if I click done the object disappear.

 

---

Hi gara, the sub-d plug-in requires the object's faces to be quads or triangles, meaning all faces should have 3 or 4 boundary edges on them.

If you have something like a 5-sided pentagonal face in your object for example, that object will not be usable by the plugin and you'll get an error and behavior like you describe.

My guess is that's what you're running into, if you're not sure then please post the 3DM model file of your object so I can take a look at your particular case.

You would need to edit the model to be made up of quad faces before you can subdivide it, you can do this by drawing in some lines and using Edit > Trim to cut things into quads, or you also might try exporting out from MoI as an .obj file using the "Output: Quads & Triangles" option (not n-gons) and then importing that back in again.

Hi Michael,

I have use a simple cube for test the plugin, so it has four edge.

I have try also a cube created in moi, but the result is the same

---

Hi gara, over here I'm not able to reproduce any problem using a cube drawn in MoI.

What error message are you seeing?

- Michael

---

I don't know if I attach the image in the right way, but the error is this

Hi gara, are you possibly running an older version of the script? Try getting the latest one named Subdiv_beta9.zip from here: http://moi.maxsm.net/media/files/ .

Also what version of MoI are you running it with?

- Michael

---

With this new version works perfectly.

There is a way to check the tangency and curvature?

---

Hi gara, MoI does not really have any tangency or curvature analysis tools currently, it's not a focus area for MoI.

But if you turn on metallic lighting and set some specular highlights on under Options > View > "Lighting options", you can look at the reflective highlights to see any major breaks.

- Michael

Ok, thank you Michael!

---

The CCC script shows some curvature lines and radii, for curves.

---

Thanks bemfarmer, but this plugin does not work with the subdivision surface

---

CCC will work for curves obtained from a surface.
The curve can be an isocurve from a surface, or a curve copied from an edge.
- Brian

---

Hi Brian, one thing to be careful about is a curve on a surface can have very different curvature properties than the surface itself.

Like for example, here's a planar surface that has curvy isoparms and edges:

Hi,

I just successfully converted a retopologized ZBrush mesh to a solid thanks to ImportObj and Subdiv. Brilliant work, Max, many thanks!

Any chance of continued Subdiv development, like triangle subdivision optimization? It would be fantastic if you could make a smoothly subdivided solid from a triangulated, decimated mesh, like the output of Zbrush Decimation Master or Blender's Decimate modifier.

Thanks again,

---

P.S.: A tip: if your mesh is fully symmetrical, import and subdivide half the mesh into MoI, then mirror and join to a solid. It will save quite some calculation time, and enable you to import larger meshes with more polygons.
