Auto Smooth

Applies Blender's Shade Auto Smooth (the Smooth by Angle modifier) to every selected mesh in one go, at the angle you choose. Any old Auto Smooth / Smooth by Angle modifier is removed first, and the fresh one is moved to the top of the stack — so a batch of mixed objects never piles up duplicates. Works in Object Mode; meshes that are in Edit Mode are handled too.

A companion tool, Clear Custom Normals, strips custom split normals from the selected meshes. Custom normals override auto smoothing, so clear them first on imported geometry if auto smooth seems to do nothing.

Hotkey: Not bound by default — assign a key in Preferences › iOps › Keymaps, or run it from the iOps pie / operator search. Also available: the IOPS TPS sidebar panel has 30 / 60 / 90 / 180 buttons for Auto Smooth and a button for Clear Custom Normals.

Options

  • Angle — the smoothing angle in degrees (default 30). Change it in the redo panel after running.

Tips

  • Non-mesh objects in the selection are simply skipped.
  • Clear Custom Normals only shows up when at least one selected mesh actually has custom normals.
