• Projects to look forward to in 2023 — blender.org

Modules & Projects

• 2023-01-05 Animation & Rigging module meeting
• 2023-01-09 Eevee/Viewport Module Meeting

Geometry Nodes

• Simulation Nodes won’t be ready in time for Blender 3.5.
• The focus now switched to the other 3.5 targets.
• New task for the development of nodes for procedural hair.
