Problem with angle Auto smooth.

Can anyone look at this please?
With some meshes I cannot set angle Auto smooth.
It cannot be highlighted.

Scroll down and in the Geometry Data panel ‘Clear the Custom Split Normals Data’

Thanks, works.
And for 1000+ objects in scene by one click :slight_smile:

Split the view and add a text window
Create a new text block and paste

import bpy
scn = bpy.context.scene
sel = bpy.context.selected_objects
meshes = [o for o in sel if o.type == 'MESH']


for obj in meshes:
    scn.objects.active = obj
    bpy.ops.object.editmode_toggle()
    bpy.ops.mesh.select_all(action='SELECT')
    bpy.ops.mesh.customdata_custom_splitnormals_clear()


    bpy.ops.object.mode_set()

Select all the objects
Press the ‘Run Script’ button on the text window header

Works great, very thanks again :slight_smile:
