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. Please please please implement support for volume refraction as well! Currently there's no way to do volumetric refraction in Cycles, to achieve effects like heat haze (air movement deforming the environment above hot objects in cold areas).

    • Exactly! I tried to model a 'ring world' (big ring spinning around the sun and people stand on the inside surface) to see how the air would affect visibility of other parts of the world and not possible.
