About Author

Bart Veldhuizen

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. Another great set of updates. The Multithreading is probably the biggest for me. Brings back more power to my Threadripper.

    I do hope we'll hear more on AMD and CyclesX soon, still concerned about lack of info on that
