Hi all,

Here are the notes from today's meeting in, #blendercoders

1) Todos and planning for 2.77

  • The updated planning and targets for the next release.
  • Meeting agrees on moving to BCon3 next meeting (27th). That means patches should then
    be applied in master.
  • Kevin Dietrich: the OpenVDB caching patch was reviewed and accepted by Brecht, unless someone
    has any objections, I can apply it in master this week.
  • Bastien Montagne: merged all ID linking fixes he dared!
  • Bug tracker has 157 open issues. A lot of work to handle all the open issues.
  • Python3.5 update is done... so unless guys report bugs we assume its all working 100%
  • Alexander Romanov will work this week on getting his patches approved and applied. Specifically: GLSL vector transform node and World texture display in viewport

2) Other projects

  • Campbell Barton's boolean code is WIP, will not replace Carve modifiers yet (for 2.77).
  • Lukas Toenne: working on compiler stuff for object_nodes. Complex stuff, not attractive to show.
  • Ton: work on 2.8 could get accelerated a bit. Especially to collect feasible proposals and designs.
    Based on that we then can decide on how to handle funding (dev fund, crowd, etc)
  • Sergey Sharybin moves to Amsterdam, will work full time for Blender Institute now.


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 ;-)


  1. Mr. Roosendaal, its possible implementing the rigging system that explains Daniel Martinez Lara in the last Blender Conference? Rigging for artist? Thank you very much for your attention.

  2. Thank you, Gurus, for your tireless dedication!

    Encouraged by
    and by Paolo Ciccone's appraisal of CUDA vs. OpenCL ,
    I dared to upgrade my 2004 iMac to a late-2015 Retina 27" model,
    with a non-CUDA AMD Radeon R9 M395X graphics card with 4GB VRAM.

    You state that Blender 2.8 will expect OpenGL 3.2,
    but DAZ Studio claims that my OpenGL is 2.1;

    will I be ready for Cycles of blender 2.8, or did I make a foolish choice?

    • You made a foolish choice. Why the hell did you get a mac?

      Radeon R9 M395X supports OpenGL 4.4 so that's no problem.

      Problem is that OpenCL is not supported well on mac and also rendering in OpenCL is no good because many features supported on CUDA are not supported on OpenCL.

      Why didn't you get nice CUDA workstation for that money..You could have got a hexcore with 32GB ram, 2 cuda cards, PCI ssd storage and two 1440p displays..

      • I'd never buy any sealed all-in-one computer (Mac or PC) that can't be upgraded, unless it were a cheap little media PC to go behind a TV. You are stuck with a spec that rapidly becomes feeble (or incompatible, e.g. Radeon+Cycles), and if one component goes wrong the whole computer is out of action for a long time. For much less than the price of the Mac, you could have had a custom PC builder put together an i7 machine with a 4K 27" monitor, 16GB RAM, a proper SSD, separate data HD, and a pair of powerful nVidia GPUs... upgradeable whenever you like.

    • Ok; opinions thus far:
        (a) stay away from Macs;
        (b) build your own machine.

      Blender developers, however, have been very Mac-friendly thus far;
      Ton Roosendaal, in particular, is a Mac user himself (am I wrong)?

      The July 2015 announcement of significant Mac-oriented contributions to OpenCL
      and to the Cycles kernel was highly praised by Ton:

      ...That means that Blender now can support the current Cycles render engine for Mac Pro (10.11)
      with similar GPU render quality as Cycles had for CUDA in the past years...

      10.11 "Capitan" is what I now have, so, let me rephrase my question:

      what is the near-term follow-through of AMD's July 2015 contribution to OpenCL and Cycles?
