  • Starting this year/January, we now have Richard Antalik working fulltime :slight_smile: (triaging at first, drifting towards VSE)

Blender 2.82 bcon3

  • Original plan is to move to bcon3 this Thursday (9/1)
  • Grease Pencil / annotation patch needs review by then - D6467
  • Lukas Stockner says at least one UDIM patch needs review, specially the Eevee/Workbench patch (D6456) - other patches: D6465 (simple), D6492 (packing, more complex, not priority) - Clement will try to look at it
  • Lukas will also work in UDIM manual in the coming days
  • Pablo Dobarro wants the IK pose brush (D6389) to be in bcon3

Blender 2.83 bcon1

  • Just a reminder that we then also start 2.83 bcon1 this week
  • Time when consider what to schedule in the modules roadmaps let’s remember of the tracker curfew
    (so devs are expected to work 2 full days a week with bug triaging, fixing and patch review)
    This will impact the inflow of new features, but it is temporary

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. If someone will soon be working on VSE awesome! I think it's important to keep VSE as a feature, but it's ok if it's out of commission for a while if that means they can build a GPU decoding, performant, multicam friendly, buttery smooth playback beast. I would love to be doing things I'm using Resolve for, but in the blender way with my other beloved tools. Right now there's nothing else on linux that has the playback and performance. One can dream for the future!
