I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. WOW! this is soo COOL! I'm going to have to really get into modeling when 2.5 comes out! What beta release is Bmesh included?

  2. Drool....

    Thank you to the developers of Bmesh. This is soooo exciting. This gives Blender even more of a move towards being able to address all the needs of artists and developers. Thank you for all your hard work. It is appreciated.

    Also thanks to the guy who made the video. I love the accent. And the burp at time index 7:01. This was great.

    On a side note, the Blender interface for 2.5 is beautiful. Man it just really looks nice. So many people are putting so much effort into this project. It's is amazing to see it develop.

  3. When can I have this!!??? Finally Blender will be able to replace all of the other 3D programs I have to use for ngons and such... Plus it should make scripting for more advanced tools easier for us novice programmers. Can't wait for a stable build, you devs are doing a great job!!

    BTW Props to the dude in the video for the voracious belch!! Awesome.

  4. Dictator HTB to the rescue!

    En gons
    En like 'N'
    and gon as in polygon

    Ngons = EnGons

    I'm a natural dictator/communist/emperor so it is, cause I say, it is!
    my subjects you may proceed to say it correctly! ;-)

  5. very nice tool !

    about the interface : even at the little size of the video the size of buttons look nearly just good, so in the real size of the interface they are very very to much big :)

    sorry my english

  6. Yes!
    Finally I'll be able to do complex architecture in blender without having to worry about zillions of polygons whenever I have a round window!!!

    All professional 3d packages I know have had this feature for ages, about time blender gets it!

    I have one question though: How will Edge Loops work now? ctrl+R creates a new edge loop, but I see no way in hell it's gonna work when a face with 10 vertexes gets in the way.

  7. if you can model while burping it's clear that blender is now even more powerful and easy ;-)
    now i have 2 questions
    1. is there any application so powerful as blender is in poligonal modeling?
    2.what about the new nurbs?

  8. Brilliant! This B-Mesh code is solving a lot of problems, including tessalation and ability to dissolve in a logical manner. Blender should have had this a long time ago, but I'm very glad it's finally here!

    Great job!

  9. ever since i heard about bmesh, i've been holding my breath till its release. it's looking soooo sweet. Thank you joe and everyone else for the hard work and thank you michael for the awesome preview. P.S. I think the burp was at least a +3, for artistic accomplishment.

  10. I like the way how he insists to the fact that this is not the goal of Bmesh to have npolygons in a final model.
    Blendies are often making the mistake.

    Thank you for this.

    Go for nurbs now :)

  11. That is sooo cool! Having excess to this from Python is such a huge leap compared to any previous version of Blender!!! Not having to work out everything on your own in Python is just fantastic! I love 2.5!

    The learning curve is quite steep, understanding how Bmesh works takes quite some concentration.

    I just made a filled circle, dissolved the central vert, selected 9 conected(loop) verts round the outside (four verts from each side of the Y axis and one on the axis) and then extruded them along the Z axis. The result is much different to what you expect, because you assume it will be like playing with a lattice modifier on the shape when in fact you notice theres no slopes!
    In other words you assume that verts on opposite sides of circle are connected, but infact the verts are only connected to those around them...

    It's getting crazy but fun...

    Hope fully at some point there will be some documentation to brief over the behavior of Bmesh, but it may be that i'm lazy and dint bother searching ;-)

  13. This is going to be really nice, I would ask to add to the menu, an option to take the selected face and move the vertices into a circle. This would cut down so much time in making perfice circles in a mesh the old way.

    Blender keeps getting better, and better.

  14. What I wanted to see is how these n-gons render out.... for example at exactly 9:00 into the video, he uses dissolve and creates a multi-sided polygon where some of the verts (i.e. the 5 at the base of the little steeple) are not in the same plane as the other 4. In 2.49b, if you create a four sided polygon and move one of the vertices out-of-plane, it doesn' t look very good in the render!
