Disclaimer: When using the list layout, since Blender 2.90, every time a modifier gets a new feature I need to manually update the layout and I may not always do that immediately. So there may be a delay.

Features

• Modifier list or stack
  • Modifiers can be displayed either as a list or as a stack
  • There are separate settings for Properties Editor, sidebar and popup in the addon preferences
  • Setting for the current layout (Properties Editor, sidebar or popup) can also be found in the Modifier Extras popover
  • Currently only the Properties Editor setting is enabled because the stack layout is not working outside of Properties Editor because of a bug in Blender
  • When switching from stack to list, the panels don't seem to get removed. Disabling and re-enabling the addon fixed that.
  • List
    • The settings of the active modifier are shown under the list, so you will see only one modifier at a time
    • The default list size inside the popup can be set in the addon preferences
    • The order of the list can be reversed persistently by enabling the "Reverse List" setting
  • Stack
    • It uses the default modifier stack, so modifier layouts are always up to date
    • Not all features of the addon are supported with the stack but most are
• Modifier search
• Modifier menu
• Favourite modifiers which can be set in the addon preferences or from a popup available from the Modifier Extras popover
• Ability to apply modifiers in edit mode (kind of). The "Apply Modifier" and "Apply All Modifiers" operators automatically switch to object mode, apply the modifier and switch back to edit mode.
• Ability to apply modifiers even if the object's data is used by multiple objects. In this case, a popup with two options is shown: "Apply To Active Object Only (Break Link)" and "Apply To All Objects"
• Operators for synchronizing one or all modifiers on instances. These can be found in the Modifier Extras popover.
• Ability to inserted new modifiers after the active one by enabling the "Insert New Modifier After Active" setting.
  • Hold control to override this. (When off, the behaviour is reversed).
  • Modifier search doesn't support overriding
  • This is really slow on heavy meshes
• Setting to disallow applying hidden modifiers, which affects both "Apply Modifier" and "Apply All Modifiers". Hold Alt to override this. (When off, the behaviour is reversed.)
• Ability to move a modifier to top/bottom by holding shift when pressing "Move Modifier"
• Modifier batch operators Toggle All Modifiers, Apply All Modifiers and Remove All Modifiers. Apply All Modifiers works also in edit mode.
  • There's also an operator for expanding/collapsing all modifier panels when using the stack
  • When using the stack layout, the operators are located either in the top level layout, like with the list, or in the popover. The "Show Batch Operators In Main Layout With Stack Style" setting controls that.
• Sidebar panels and a popup, which contain also a vertex group list. The sidebar panels can be disabled in the addon preferences. The Sidebar category can be customized and there's also a setting to keep the panels always visible.
• Object pinning for the sidebar tab and for the popup by clicking the pin icon in the header. When an object is pinned, the panels don't follow object selection but keep showing the modifiers (and vertex groups) of the pinned object instead. It works the same way as context pinning in Properties Editor.
• Easy way to add a control object - or as I decided to call them, a gizmo object - to a modifier
  • There is Add Gizmo button for adding a "gizmo object" to a modifier. It basically just adds an empty and assings it to the appropriate property of the modifier (Mirror Object for Mirror modifier for example).
  • All gizmos go into a gizmo object collection
  • By default, the gizmo is placed at the origin of the active object. But if you are in edit mode and have something selected, the gizmo is placed at the average location of the selected elements (for meshes and curves).
  • If you hold alt while you click the Add Gizmo button, the gizmo is placed at world origin
  • If you hold shift while you click the Add Gizmo button, the gizmo is placed at the location of the 3D Cursor
  • You can also hold shift when adding a modifier to add a gizmo at the same time, so you can save an extra click :)
  • After adding a gizmo, the Add Gizmo button changes to a visibility toggle and a settings popover, in which you can change some gizmo setting, such as its location, rotation and parenting. You can also select or delete the gizmo from the popover.
  • When using the stack layout, gizmo settings are in the Modifier Extras popover
  • There is a setting in the addon preferences for automatically parenting the gizmo to the active object on addition
  • There is also a setting to automatically match the size of the gizmo to the object. Note: this can be a bit slow on heavy meshes.
  • You can hold shift when applying or removing a modifier to also delete its gizmo
• Improved UI/UX for Lattice modifier
  • A lattice object can be added to a lattice modifier by using the Add Gizmo operator or by holding shift when adding the modifier
  • It goes into the gizmo object collection
  • It's automatically scaled to fit to the active object or to the selected elements if the object is in edit mode and at least two vertices are selected. A vertex group is also automatically created from the selection.
  • The lattice is aligned to the object. Unfortunately, there's no auto alignment or any way to define the alignment currently.
  • The lattice automatically goes into edit mode when it's added
  • You can go in and out of lattice edit mode by by using the Edit Lattice button. It automatically utilizes object pinning, so the modifier settings keep being shown also when you're editing the lattice. Note: this operator doesn't fully support redo.
  • The settings of the lattice object are shown among the modifier settings, so everything is in the same place
  • When applying or removing the modifier, hold shift to remove the lattice object and the vertex group (unless the group was manually created and its name doesn't start with "ML") at the same time
  • If for some reason the context pinning doesn't automatically turn back off, just click the pin icon in the header to unpin the context
• Customizable modifier default settings
  • They can be found in the addon preferences
  • In some cases one setting affects another, which can be confusing. Example: Wertex Weight Proximity's proximity_geometry enum's 'FACE' option is synched with the invert_mask_vertex_groupin setting. Hopefully these kind of situations are rare.
• Extra settings/operators for boolean objects inside Boolean layout: visibility toggle, display type, shade smooth / shade flat and select
• Auto Smooth is enabled automatically when you add a Weighted Normal or a Normal Edit modifier
• Black and white icons to choose between

Hotkeys

Default hotkey for the popup is Alt + Space. Inside the keymap editor, you can find it under 3D View > 3D View (Global) > Modifier Popup.

In the Property Editor, Shift + A opens the modifier menu and Shift + Ctrl + A opens the modifier search. To disable or add shortcuts for them for other editors, use "object.ml_modifier_add_from_menu" and "object.ml_modifier_add_from_search" in the keymap editor.

It's recommended to add shortcuts under the 3D View > 3D View (Global) category so they are availabe in all modes.

Preferences are auto saved into your Blender config folder

• Example path: "...\AppData\Roaming\Blender Foundation\Blender\ < blender version > \config\modifier_list\preferences.json"
• Preferences from another version can be imported using the "Import Preferences" operator
• This means disabling Modifier List won't make you lose your settings

Installation

1. Go to Edit menu (File menu in 2.79) and open user preferences
2. Switch to Addons tab and click Install...
3. Navigate to where you downloaded the zip file to, select it and click Install Add-on from File
4. Enable the add-on by ticking the checkbox next to its name
5. Save user preferences

Known Issues and Limitations

• Inside the popup, lists don't remember their sizes after they are resized. Popups are not really ment for this kind of stuff, so that's a limitation of Blender.
• Using the popup, picking an object from viewport is not possible. A limitation of popups. Hopefully that could be possible at some point because that applies also to the driver editor popup and there's an open bug report about it in the bug tracker.
• Warnings like "Enable 'Auto Smooth' option in mesh settings" are not displayed
• Data Transfer's "Generate Data Layers" doesn't use automatic settings, instead it opens a menu
• Add Modifier's tooltip doesn't fit to Lattice
• Custom bevel profiles don't get synchronized when synchronizing modifiers between instances
• Geometry Nodes doesn't have the Internal Dependencies panel
• Move to Nodes and Copy to Selected operators don't work in the popup or in the sidebar if an object is pinned

modifier_list's Issues

bug: can't register add-on because of corrupt prefrences.json file

Hi there, today my modifier list stopped working.
After some research I found out whats causing the trouble.
My preferences file is zero kbyte.
I don't know how that happend....
Anyway, once the addon tries to read that prefs file it runs into a error.
Could you add some safety checks to avoid issues like that?

regards.

btw. i'm using Blender Version: 2.93

Feature Req: Discard disabled modifiers before using "Apply all modifiers" or "Apply Modifier"

I sometimes will disable a modifier (such as a subdiv modifier), and leave the modifier. (Disable realtime viewport and render)

Well, whenever I apply all modifiers, or apply the modifier, blender's default behavior is to re-enable the modifier before applying it.

I consider that undesirable. Can you add an option in your addon to automatically discard modifiers that are disabled in realtime viewport before applying the modifier?

Additionally, can you add a popup warning that says something like, "some of your modifiers are disabled in the realtime viewport, but enabled in render, how would you like to proceed?"

Option A: Discard modifier(s)
Option B: Keep modifier(s) & apply

This, to me, seems like a fool proof way to ensure that the user doesn't accidentally apply a handful of intentionally disabled modifiers when applying all modifiers.

Thanks!

Not working properly in Blender 4.0.2 and above

Copying Modifiers not working, Cannot Remove Modifiers etc.

There is no "toggle edit mode visibility" in boolean modifiers when in list mode

Issue

Tested with 1.7 and 3.0 blender daily build

Blender 2.90 - Cannot apply all modifiers

Issue

When trying to apply any modifier or apply all modifiers, I will get errors like the mentioned above. Apply_As seems to not be recognized.

Blender Version: 2.90 Alpha

Blender 3.3 Hair Nodes conflict

I know 3.3 is still in beta, but wanted to bring forth an issue I observed with this addon and the new hair nodes modifiers.
When having the addon set to "Properties Editor" it will hide the new modifier for the geometry node Hair Curves.
The best way around this currently is just using the sidebar option.

Edit: I also want to add I did update to the latest version despite what's showing in the video below. Same behavior on latest.

Weld Modifier - Missing Max property

Issue

There is a missing property in the weld modifier that pulls a console error:

C:\Users\drais\AppData\Roaming\Bforartists\Bforartists\2.91\scripts\addons\modifier_list\modules\ui\properties_data_modifier.py:1672 rna_uiItemR: property not found: WeldModifier.max_interactions

Task

Find out where the RNA is or remove the property.

Info

Blender 2.91 Beta / Bforartists 2.5.1

Geometry Nodes - Object Input and Collection Input fields greyed out.

Expectation

Expected result, input for objects and collections to be able to pick (from the modifier stack.)

Issue

Tested in 2.93 and 3.0 with version 1.6.4

Library override disables all rows

In the image below I first disabled the Modifier List addon and changed Vertices just to check that they are actually editable in the default layout. Then I reactivated the addon and all modifiers are uneditable.

No output attributes in the geometry nodes modifier

The output attribute of the Geometry Nodes modifier works with errors, it is necessary to switch List to Stack.

There is also a problem with deleting modifier after these switches

Geometry nodes modifier Outputs / Inputs not displayed correctly

The addon is amazing hence I want to report this bug to make it even better. The geometry nodes modifier is not displayed correctly (blender 3.0.0, modifier_list 1.7.2).
The input and output attributes are not listed and nameable.

Minor Issue occuring when there is no objects in the scene

As stated in the header, minor error arising when there is no objects in the scene at all, and when the cursor is placed in the Outliner Context.

That's nothing serious really, but still, found a solution to this issue by adding another check condition to the "Poll" function.

Blender crash if i use modifier list and constraints.

String input in Geometry Nodes is not Shown

Hello Antti,

first of all: I absolutely love Modifier List, and in my opinion, it should be standard UI for modifier in Blender.

To the bug:

With Modifier List 1.7.4 and Blender 3.4.1 the input for Strings in the Geometry Node input is not visible.

Thank you.

Supporting the project

Hi,

This is one of the most useful UX-improving Blender addons I have. Is there a way I can express my gratitude and support? Like, a Gumroad page or something.

'Toggle Visibility Of All Modifiers' shortcut doesn't work in edit mode.

Button works in edit mode, but after assigning shortcut to it shortcut doesn't work. Outside of edit mode everything works fine.

Can't identify modifiers without memorizing icons

First off, this is an awesome addon, very much appreciate the efforts. <3

Second, actual feature request/bug: Currently, if you rename a modifier, there's no way to find out what type of modifier a modifier is, unless you have the icon for that particular type of modifier memorized (or pull up the modifier list again to compare). It would be really nice if there was some way to directly identify what type of modifier a given entry in the list is, without requiring humans to do heuristics.

If the blender API allows for it, the fix might be as simple as adding a tooltip to the icon next to the modifier. I'd be quite happy with whatever you'd care to support, though. Not picky!

The GP Object Modifiers appear in Modifier Properties Tab of other Object (mesh object) 2.93.4 & 3.0 Alpha, macos 10.13.6

The first, thanks for this useful addon!!

I found an issue if in the scene there is a Grease Pencil object with modifiers, these modifiers appear too in the Modifier Properties Tab of the different objects (mesh objects) in the scene.

Steps:

You have to check 'List' option in Preferences Addon > Style > Properties Editor, with 'Stack' option the issue doesn't appear.

1. Open a new file with the Cube.
2. Add a GP object, for example, Suzzane
3. Add some modifiers to Suzzane
4. Select the Cube and go to 'Modifier Properties Tab'
5. The modifiers of Suzzane appear

List View breaks some Geometry Node Inputs

When building a Circular Array Geometry Node Template I had some custom Group Inputs not being recognized.
Troubleshooting that problem I traced it back to the Modifier List Addon, which I love.

With the List View being active, several inputs just don´t work.

List View OFF:

Thx for the awesome addon.

Update to Blender 3.0.0

Issue

I found that with the dev builds of 3.0.0 the version string to float of the BLENDER_VERSION_MAJOR_POINT_MINOR has to be 3 characters, not 4 to work.

Example Fix

modifier_list_1.6.4.zip

Bug: Modifier UI not loading for Areas in separate windows

Blender version: 2.81 Stable
OS: Win10 Pro 64bit
Modifier List v1.4.2

Whenever I restart Blender, the modifier area is empty. I am assuming it has to do with the area being inside of a separate window. This just happens to be how I prefer to use Blender because I can maximize the 3d viewport without losing view of my outliner and properties editors.

Toggling this option OFF/ON causes it to load.

Hopefully this is an easy fix! :)

The move through the hierarchy icon is not reversed when you turn on the inverted mode.

Script works excellent. That is just a little issue.

Hook Gizmo has parent transformation applied

If you add a hook modifier and create a gizmo, it gets created at the parent object's location, and therefor: with all of its transforms. This means to if you have an object that exists at z 3, the hook object will start with said transformation applied already.

AttributeError: 'Context' object has no attribute 'object' File "C:\Program Files\Blender Foundation\bl_symlink\scripts\addons\modifier_list\modules\properties.py", line 13, in modifier_active_index_get Traceback (most recent call last): File "C:\Program Files\Blender Foundation\bl_symlink\scripts\addons\modifier_list\modules\properties.py", line 14, in modifier_active_index_get ob = get_ml_active_object() File "C:\Program Files\Blender Foundation\bl_symlink\scripts\addons\modifier_list\modules\utils.py", line 47, in get_ml_active_object ob = context.object AttributeError: 'Context' object has no attribute 'object' File "C:\Program Files\Blender Foundation\bl_symlink\scripts\addons\modifier_list\modules\properties.py", line 13, in modifier_active_index_get

both seem to be not critical for the add on to work, but would be nice if they could be fixed / prevented
blender 3.3.3 lts & modifier list 1.7.4

thanks

Issue Installing 1.7.5

Right now the installation zip doesn't install to a sub folder for the __init__.py to register - and when I try to get the addon to register I get an issue, might be likely due to the parent folder name?

A unkonwn modifier on modifier UI

There is a new modifier named Surface when I enable the addon. If I try to add it, it will show:

"Cannot add Surface modifier for this object type"

Is it a bug or a function of addon? Look forward to your reply. Thanks.

Add a option to customize the tab

Hi.

With more and more add-ons adding a tab in the N panel, the later can easily become vertically overcrowded by tabs (especially if the user has many addons activated).

To get rid of this annoyance (with many tabs on the N panel, it can be difficult to read the titles of these tabs), some users might want to place your add-on in the Edit or in the View tab... (or elsewhere).

Here is a related topic about this issue: https://blender.community/c/rightclickselect/dzdbbc/

According to the number of votes, there are many Blender users who are annoyed by this issue. The only workaround (for the moment) is to add an option in the addon preferences.

Could you please add an option in the add-on preferences to give the user the choice of the location of the tab (in the N panel) ? (in order to move the add-on from its own Modifier List tab to a custom one).

---

Maybe you could have a look at the source code of these (free) add-ons (to reuse the lines related to this feature)?

Thank you in advance for considering to add this option.

Eyedropper selection seems disabled for all modifiers when using the Modifier Popup

I noticed this first with the Shrinkwrap. When using the Modifier popup I'm unable to click on the target eyedropper icon to select a target from the viewport. I can only click on the target box to bring up a list to choose a target. If I forego the Modifier Popup and use Blender's standard Modifier Properties window, eyedropper selection works fine.

I checked with other modifiers that have eyedropper controls and they too seem to be disabled when using the Modifier Popup screen.

I'm using version 1.7.4 of the addon and Blender 3.1.2.
