NOX Renderer is now open source


The NOX physically based renderer has been released under an Apache license.

After years of development we decided to give NOX for the community.

NOX physically based renderer, fully integrated with Blender and 3ds Max (and with C4D support) is now Open Source. We release it on Apache license - free to commercial use and modifications.

You can freely improve and modify this render engine, integrate it with any 3d software, write plugins for NOX, use it in your commercial works and / or sell it. The possibilities are endless and depend only on you.

Main features of NOX:

  • physical based engine
  • enhanced postprocessing
  • rendering to layers
  • real and fake dof
  • instancing and displacement
  • subsurface scattering

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 ;-)


    • FOSS is rarely about whether you pay for something or not, it's about e.g. being able to build your work pipeline depending on something that isn't forever subject to the whims of one company.

      I'm sure users of software which has recently been acquired by Autodesk know what I mean.

    Always a wonderful decision to open-source new programs! So now Blender has yet another FOSS raytrace renderer... I wonder how this one does compared to Cycles.

  2. Awesome, its good to see another renderer joining the ranks of Cycles, LuxRender and Mitsuba. If anybody is having trouble with the NOX installer (it downloads but cannot open because the file extension type is invalid like mine was) just rename the file getting rid of all the dots in the file name and type .exe on the end, it worked for me.

  3. Nice! Very generous of its developers! I started using it a few years back, but along the way, after installing so many Blender releases, I just sorta' forgot about it. But now, I'll definitely get back to keeping it around. You can never have too many renderer options, I say! Thanks, Evermotion!

  4. I have been curious about these physically based renderers, versus Cycles, and how to make materials for them (pbr materials), now I can try it with NOX, thanks!
