I've seen some sliders working in pie menus but the one I'm trying to add to my pie script isn't showing up. Its the 'autosmooth normals' slider from the Object Data tab, under Normals (in the Properties panel).
I'm trying to call it directly in the pie menu without making a new class since its already loaded by the main UI:
row.prop(mesh, "auto_smooth_angle", text="Angle", slider=True)
Are sliders like this one not able to be displayed in pie menus?
