Blender developers meeting notes - 2018-12-10


Here are the notes from this week's developer meeting.

New Features and Changes

This week was mostly about bug triaging and fixing. By my estimate about 120 bugs were fixed this week.

  • Cycles GPU rendering now has support for NVIDIA Turing cards (RTX 20xx and similar). Note this is using CUDA still, not the raytracing hardware units at this point.
  • Cycles OpenCL rendering on macOS is no longer supported (mail).
  • Animated values that have been modified but not keyframed now get an orange button color.
  • Render metadata now has an option to include the hostname, useful for render farms.
  • Shader node editor now includes materials settings panels, so all material work can be done in one editor.
  • Wireframe drawing got many optimizations, both for faster drawing of heavy scenes and when using low end hardware.
  • Grease Pencil has a new arc primitive tool.

Merging Branches

The proposal is to do the following:

  • Rename master to blender2.7 branch, blender2.8 to master.
  • All git history is kept, since it is valuable even if it makes bisect harder.
  • "BF Blender 2.8" bugs will be moved to "BF Blender", to have a single tracker. These are already quite mixed up anyway.
  • We keep supporting blender2.7 to more or less the same (minimum) level as we do master now, to ensure there is a production-ready Blender version being maintained.
  • The blender2.8 branch could be deleted and blocked from being recreated on the git server? To avoid users and developers using the wrong branch by accident.

If any developers disagree with this, let's discuss it. Otherwise, we'll do the merge in the coming week or two.

Other Projects

The developer wiki has a new theme.

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. the cycles macOS situation is super disappointing, although it makes sense; I can confirm OpenCL performance on macOS was basically useless as it stood.

    any chances of a metal programmer out there? with apple not playing nice with Nvidia, the Mac situation is looking pretty dire. :(

  2. Developer team added many new features to blender 2.79 experimental version.
    so when we can see this features as a main stable release ?

  3. It's a shame that OpenCL / macOS is such a mess. Their loss, I guess. I know a lot of 3D artists that are leaving macOS for Windows due to situations like that.

    As always, I love reading these updates and keep up the sterling work everybody.

  4.  Particle System
    ・Number of particles
    I want to dominate the key frame sensuously
    Current Design:”Number of particles” per Between frame and frame
    Please do it:”Number of particles” per Minute
    ・Particle Instance (Modifier)
    Please implement ”Try to monitor between frame and frame”
    For example, the influence of physical calculation and velocity
    ・Everything Nodes
    Please implement ”Try to monitor between frame and frame”
    Please also be able to bake the bone's animation
