Hello. When I select the 4 vertices of a face and I press the subdivide button the face gets subdivided in 4. Is there a way to subdivide over an axis or something so I end up with 2? ie:


This is what happens now:

*------------------*                  *--------*---------*
|                  |                  |        |         |
|                  |                  |        |         |
|                  |                  |        |         |
|                  | => subdivide =>  *--------*---------*
|                  |                  |        |         |
|                  |                  |        |         |
|                  |                  |        |         |
*------------------*                  *--------*---------*

I need this:

*------------------*                  *--------*---------*
|                  |                  |        |         |
|                  |                  |        |         |
|                  |                  |        |         |
|                  | => someway   =>  |        |         |
|                  |                  |        |         |
|                  |                  |        |         |
|                  |                  |        |         |
*------------------*                  *--------*---------*

Thanks in advance.

Method one:
Scale it down on the axis and select the two vertices on the right. Then extrude those two vertices out.

Method two:
Select all four vertices and hit ''X'', ''Only Faces''. You can then Subdivide the top edge and the bottom edge. Select the two left edge vertices and the new middle vertices and hit ''F'' to make a new face. Clear the selected vertices and select the right two and the middle two and hit ''F''.

There is another way. Select all the vertices for the face, then click on the ''Beauty'' option in the edit menu. Then subdivide.

yspotua: Hey, this is cool. It subdivides the face horizontally. How do I do to subdivide it vertically? Maybe it is obviously easy but I'm kinda new to this...

EDIT: Heh, one way to achieve it is rotating the view

I don't how you could specify the vertical subdivsion. You may have to do it manually by subdividing each edge and then creating an edge from 2 new vertices.

Try the Blender knowledge base at http://www.vrotvrot.com/support/browse.php. If can't find it there, then try the forums at www.elysuin.com, there are a lot more experience Blender users there.

Thank you very much

Now I''m in teh hard process of leeching textures all over the interweb...

Let me share my texture-leeching secret with a fellow Blenderhead:
I go to the library and check out 3D modeling books. It can be books about 3DMax, Maya, Lightwave, AutoCAD, whatever. Almost all of them come with a CD of tutorials, sample files, and a bunch of textures. I can''t use the other stuff, but my texture collection has become really large and well stocked by doing this.

You may want to google for the Blender Manual 2.0 in PDF download or something. It's free for download now, which used to cost 10 bucks. It's a really well written manual, covering most, if not all, of Blender's wonderful features.

Download Blender 2.27 if you already haven't, it's a bit more stable than 2.26. They still don't have the game engine back in it, which was pretty cool from what I've seen, but honestly I could care less.

Elysiun - go to the Forums section of this site to see some great some from some Blenderheads. WIP section or Finished projects section is where I'll be posting whenever I learn more. You can even learn about Python scripting from the Python forum, or get a list of tutorials on the Help forum, etc... It's all good.

Hope that helped a bit.

EIDT - Here's a direct link to the PDF download (free of charge) - Clicky.
EDIT - Oh, and if you want the Gzip version of that just add .gz instead of .zip to the end of the URL.

Blender 2.28 is out now. You might want to pick it up, a good few bug fixes are in it.

mmmm, I still can''t find a way to subdivide a group of faces...

Here is a screenshot, the red line is the subdivision I want to make, I tried turning "Beauty" on and then pressing subdivide, but I get vertical subdivision only...

Until Blender get better tools, you will have to divide those faces manually by selecting the edges and subdividing, then connect the points created. A little trick I used when I had bunch of edges to subdivide is to select edges that together don''t make a face and subdivide, then select the remain and subdivide.

It was this kind of frustration that drove me to use Wings(www.wings3d.com) for my organic modeling. As it is primarily focused on modeling only, it has tons of tools. To make the subdivision like you are trying to do in Wings, you could select all the edges in that row, then perform a ''connect'' command and then you would have a new edge loop.

I still use Blender to model stuff like chairs, and other squareish props, but I am just more productive use Wings for characters.

But don''t take my experience with Blender''s modeling tools to be the final word on the matter. Go to the forums at www.elysiun.com and ask this in the Q&A forum.

Oh, sad thing.

I''m learning Wings 3D too but I couldn''t make the python scripts work in blender to import from Wings, I installed Phyton and configured the enviroment variables but it throws this strange error:

Traceback (most recent call last):
File "objimport.py", line 12, in ?
File "D:\Programas\Python23\Lib\os.py", line 282
yield top, dirs, nondirs
^
SyntaxError: invalid syntax
D:\Programas\Python23\Lib\os.py:282: Warning: ''yield'' will become a reserved key word in the future

So I went back to Blender, but it seems to be that I''ll have to see how to put those python scripts to work...

The old obj scripts won't work in new versions of Blender (newer than 2.23) due to changes in Pyton API.

Here is a link to new script that works with newer versions of Blender. http://www.clubinfo.bdeb.qc.ca/~theeth/objIO_288.py

For best results you should change all of the faces to the same material. Then export in Wings. You will need to open the obj file with a text editor and make some minor adjustments.

Open the file look for lines that begin with the following:

mtlib
o
g
usemtl

You will need to put a # in front of these lines and save. The reason for this is that the programmer has not added support for importing textures.

Another option would be to use that old script that you have with Blender 2.23 or earlier.
