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. Nice job, Bassam. Until the curve bug is fixed, this looks like a promising workaround. I hope it works as well for animation.

  2. Matt, yes bug fixes are great and all, but then what happens to the nifty, esoteric tricks that you can only learn about by reading Blender Nation? =D

  3. Hey, that's pretty nifty.
    And yes, Matt, I am planning to eventually finish the curve normal fix :-) I'll hopefully get a chance to work on it this weekend.


  4. this is a good trick but for curves that go in all directions there is no good position! Have at it Ben, we'll thank you for letting us leave this chapter out of the "Blender Work-a-rounds" manual.
