System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060 Ti/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 546.33

Blender Version
Broken: version: 4.1.0 Alpha, branch: main, commit date: 2024-01-08 22:16, hash: f42071c793b0
Worked: Any versions previous to 4.1

Short description of error
The new autosmooth system has created a regression in workflow.
Instead of autosmooth being something that automatically happens, it's now something you have to be continuously applying over and over and over again.
While modelling, it creates unwanted marked sharp edges which forces the user to stop and continuously clear sharp edges and/or reapply autosmooth. Auto = automatic. This is no longer automatic.
This is a major regression in a modelling workflow.

Exact steps for others to reproduce the error
It should be pretty self explanatory based on videos provided

Hi, thanks for the report. New Smooth by Angle modifier has been added in replacement of old auto smooth property. Adding modifier might fix the shading problem, can you check?

Oh ok. So don't use the right click 'shade smooth by angle' because of the above mentioned problem.
And instead use the modifier. So if you have 100 objects you just have to individually add 100 modifiers to 100 objects, individually, one at a time?

As far as I understand, smooth by angle operator from context menu is only operating on faces currently present in mesh data. So extruding new face possibly won't update the sharp_edge/sharp_face attribute
While Smooth by angle modifier will replicate the old auto smooth property behavior 89e3ba4e25

So if you have 100 objects you just have to individually add 100 modifiers to 100 objects, individually, one at a time?

If file is created in 4.1, yes.
If file is created in 4.0, versioning code will automatically add smooth by angle modifier

I might have misunderstood something here. So I'd ask @HooglyBoogly for the info 😅 (uploaded test file, just switch to edit mode then extrude selected face)

Right-click option is absolutely useless. Its without any practical use. Modellers dont work like that. I suspect it only exists because auto smooth modifier doesnt work with instances and realizes them. Creating MAJOR regression. That should be prevented and "Shade Smooth by Angle" operator in context menu should be adding modifier instead of one-time thing to avoid current terrible UX

The new right-click autosmooth operator is not practical and does not automatically smooth.

Having to add a modifier is even slower than any right-click autosmooth.
Especially if the properties panel is displaying something other than modifiers. And with the new categorized add modifier menu, even slower.
Having to move the mouse away from the 3Dviewport is an instant regression in workflow and having to manually add modifiers one at a time to multiple objects is a workflow regression.

With the old right-click autosmooth it only took 0.5s to enable autosmooth.
With the new system it can take upto 3.0s.
That is a 500% decrease in workflow performance.

My initial report still stands :)

Hi, thanks for the report. New Smooth by Angle modifier has been added in replacement of old auto smooth property. Adding modifier might fix the shading problem, can you check?

This modifier, if you open the project in Blender 4.0 or lower it won't work at all, is there anything planned? Or will it break backwards compatibility? I noticed that it's a group node and not a Native node, so I liked the idea, except if you save this and open in Blender 4.0 or lower this doesn't work properly.

I really don't understand if it's a bug, or compatibility is breaking so quickly since 4.0 --> 4.1

@Andrew_D hi, best to continue discussion about this in #118118 🙂

Raising the priority for now.

Maann. If this new right click autosmooth behavior doesn't get fixed, alot of people are going to be unhappy. Just saying.

Has anybody put any thought yet towards how a user is going to add 100 smooth by angle modifiers to 100 objects?
Im working on an imported spaceship model atm where all objects need a smooth by angle modifier. It almost appears as though no remedy has been implemented and this is still a UX/workflow regression

@tmp88
if you have copy attribute addon enabled, you can copy selected modifier

I agree this is a workflow regression due to many reasons, but for now if no one is fixing it, you can only use those workarounds.

Where's the addon to remove all 100 smooth by angle modifiers?

I'll close this in favor of a design/todo task with specific solutions: #120230

I'm in the process of implementing a few of them, but time has been limited so far with other things coming up, so progress has been a bit slow.
