Modeling & UV

  • The "Auto Smooth" option has been replaced by a modifier node group asset (89e3ba4e25).
    • The base state of meshes is now the same as having "Auto Smooth" on with an angle of 180 degrees in older versions:
      • Face corner "split" normals are calculated when there is a mix of sharp and smooth elements.
      • Custom normals are used if available.
    • The modifier node group asset sets sharpness by the angle between faces.
    • Blender automatically chooses whether to calculate vertex, face, or face corner normals given the presence of custom normals and the mix of sharp/smooth edges and faces.
    • In edit mode, "Select Sharp Edges" and "Mark Sharp" can be used to set sharpness, or "Shade Smooth by Angle" in other modes.
    • For more information on the procedural smoothing modifier, see the Nodes & Physics section.
    • For more information on the Python API changes, see the Python API section.
  • A render "simplify" setting adds the ability to turn off calculation of face corner and custom normals in the viewport (912c4c60d8).
