  • Sergey Sharybin will see to it Mantaflow gets fixed by Sebastián Barschkis.

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.

    Animation nodes by default, please in 2.83. It is a powerhouse and an essential part for motion graphics. All big 3d applications have motion graphics capabilities. Integration should be easy enough.

  2. This is all great, but the main problem with Blender as I see it it is not still production ready for bigger projects. What needs special attention is IO update (alembic/usd/openvdb ; streaming not injecting input data), scene assembly capabilities (instancing, proxies, scattering); overrides/isolation/encapsulation of certain scene aspects (models,lights,simulations). Most of all, a clear long term development strategy.
    We can do many things in Blender, but for certain tasks, a hacker's approach is needed - you can't have more than 1 simulation in a scene active (you can stream from different scenes), scattering is done via particles and variation mostly relying on weight maps (for huge scale worlds inaccuracy is significant here). Etc etc.
