From reading the error it seems as if one file tried to use another one which was from an older version of the addon. That’s weird. Do you still have some older version(s) installed? If you have, uninstall them. (I don’t know how they could get mixed though.)
If thats not the case, can you go into the modifier_list folder in your addon directory (the path shows in the error), open a file called “addon_registration.py” and see if the lines 178 and 179 look like the following:
Glad you like it. Be aware, though, that the Boolean modifier layout is out of date in 2.91. It doesn’t have the new solver option or the new collection option. I’ll have to release an update soon.
Will it be possible to make the actual list of active modifiers drag and drop?
It would also be cool to have an option to separately disable and enable the Modifier Favorites menu so that we have the option of keeping it and using the new stock system at the same time.
Amazing addon by the way, it’s really helped clean up my workflow with modifiers.
Amazing addon who should be by default in blender in my opinion.
Will it be updated to version 2.91 with the new options for subdiv, volume mesh and volume displacement ?
I’ll update this at some point but better if I don’t give a date. I already said soon a month ago.
I haven’t used Blender for a while but I’ve followed the development so I should know what is missing.
Removed Simulation modifier as it’s no longer in master. It was available for the point cloud object which is not there anymore either. (Point cloud object will come back later, currently it’s only in the geometry-nodes branch.)
Removed modifiers from point cloud object. It currently has only one modifier in the branch: Empty/Nodes modifier. Support for that will come later.
Multires:
layout was improved by moving all options to the left column in order to make the columns more even
“Rebuild Subdivisions” operator is now hidden when there’s already subdivisions
settings are now set inactive the same way as in the regular UI
“Optimal Display” setting is now above the “UV Smooth” option
Subdivision Surface:
“Quality” setting is now visible also when Cycles experimental features are enabled
settings are now set inactive the same way as in the regular UI when using Cycles adaptive subdivision
Let me know if there’s anything missing or something doesn’t work.
With Blender 2.90.1 and Blender 2.92 alpha, to install the new version:
I remove Modifier List 1.6.1 with the “Remove” button
I click on the “Refresh” button
I “Save Preferences”
Then I install the new version with the “Install” button (as usual, selecting the “modifier_list_1.6.2.zip” file), then this error appears:

After Blender is restarted, no problem, the add-on looks correctly activated.
I guess, to avoid seeing this error, Blender users have to remove the old version, save preferences, restart Blender and finally install the new version.
Yea, that issue is related to my automatic class registering. The solution doesn’t work well when one module imports something newly added (function in this case) from another module. In that case it requires a restart to start working. I might try to solve that problem in the future. (I would need to somehow sort the modules topologically before reloading them or something.)
Thanks for the update @Symstract, much appreciated. I was a little afraid when you wrote this…
… Modifier List development would diminish.
A question: when I choose Apply to all objects when a modifier is on a linked object, the modifier is still present when I select the other linked object. I’m using Blender 2.9.1.
@Symstract, I just wanted to chime in with words of thanks regarding this update!! This has become an essential part of my blender setup and I was bummed as of late when it got broken!
Actually, is there a way I can buy you lunch or a drink? Do you have an account on Gumroad?
@Metin_Seven
The operator just copies the mesh of the selected object and applies the modifier and then switches that same mesh to the other instances. Maybe that can be improved in the future.
@0rAngE
There’s no way to donate currently but thanks for asking!
Hey, I’m looking for a way to force specific options as defaults when adding the subdiv surface modifier to an object (‘boundary smooth:keep corners’ and ‘use custom normals’).
Is this something that can be done by editing your addon’s source code? And could you point me to the relevant section?
In modules > operators > modifier_add.py, before or after
48 # Enable auto smooth if modifier is weighted normal
49 if self.modifier_type == 'WEIGHTED_NORMAL':
50 ob.data.use_auto_smooth = True
you can do stuff based on the modifier type. Like this:
mod = ob.modifiers[-1]
if self.modifier_type == 'SUBSURF':
# the following line isn't needed if you only use 2.91 or higher
if float(bpy.app.version_string[0:4]) >= 2.91:
mod.boundary_smooth = 'PRESERVE_CORNERS'
mod.use_custom_normals = True
It could be nice to have an easy way to define the default setting for each modifier. Or maybe even have different variations (maybe that would be an overkill).
WOW, very good stuff here.
Can we have the ability to click and drag to rearrange modifiers order, like in default modifier tab.
Thanks for this amazing addon.
Be aware, though, that the Boolean modifier layout is out of date in 2.91. It doesn’t have the new solver option or the new collection option. I’ll have to release an update soon.
