New Features and Changes

This week was mostly about bug triaging and fixing. About 80 bugs were fixed this week.

  • NLA: insert keyframes now works correct for blending modes other than replace. This fixes an old problem, making the NLA much more practical as a tool for animation layering.
  • Preferences: new option for header position at top/bottom.
  • Grease pencil: new curve primitive tool (video).
  • Optimizations for production .blend file loading, together around 10-25% faster on Spring files.
  • FFmpeg: enable multi-threaded encoding of multiple frames, for a ~20% speedup.
  • EEVEE: improve bent normal calculation for more accurate indirect lighting.

Other Projects

  • Richard Antalík is the new maintainer of the video sequencer. He has done work towards real-time playback, with a cache and proxy management rework in progress already. Welcome! (mail)
  • Bastien will do the first code review of mantaflow.

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. Preferences: new option for header position at top/bottom.
    how it's work?, I can't find any different when I press shift + F1-F9.

  2. Would they have time to port the shadow catcher to EEVEE? Is there a way to use both renderer using Cycles to render the shadow catcher and EEVEE for the rest? I would like to render scenes using EEVEE and compose them inside HITFILM and I need an alpha channel in my images...

    At least EEVEE can render with an alpha channel now, but the shadow catcher feature of Cycles is missing. Found a video that show how to fake it but is too restrictive.
