(Edited June 10, 2021) I'm sorry for typos. Corrected the description.

System Information

Graphics card: GeForce RTX 2080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 462.59

Blender Version
Broken: version: 2.93.0, branch: master, commit date: 2021-06-02 11:21, hash: 84da05a8b8
Worked: none

Short description of error

{F10163153, size=full}

When you add a Visual Effect to Grease Pencil object created with Library Override, you cannot change the parameters.

For Modifiers, you can change the parameters of the newly added one. I expected the same behavior for Effect.

Exact steps for others to reproduce the error

First, create a GPencil object:

Open new file
Shift+A -> Grease Pencil -> Monkey
Select Suzanne
Add a new Visual Effect (e.g.: Blur)

Save to .blend file

Next, link the above file from another file:

Open new file
File -> Link
Specify the above .blend file and the collection
Select linked Suzanne
Object -> Relations -> Make Library Override...
Open "Visual Effect Properties" tab

Now when you add a new Effect, the parameters are grayed out and cannot be changed.
(I think it should be editable.)

Also, if you hover the mouse cursor over the input field, the following error message will be displayed.

Disabled: Cannot edit this property from the override data block.

@mont29 Could you take a look at this? Not sure if this is a non supported feature as override materials.

This is just missing RNA code...

Will keep the 'adding new shaderfx to an override' for later though (process will be similar to the one for modifiers, but we need to refactor this one first, so better not add more to this for now).

I have confirmed the issue is fixed in the recent daily build (blender-3.0.0-alpha+master.461ba4438f90-windows.amd64). Thank you!

However, "Name" field is still not editable. Shouldn't it also be editable?

@muratagawa no, names are used to link overrides to their original linked data, so they must not be editable.

Excuse me, my explanation was insufficient.

I thought the "Name" field of Visual Effect added after Linked Override should be editable -- like Modifiers. Is this wrong?

I'll explain it with images. I checked it in the recent daily build (blender-3.0.0-alpha+master.461ba4438f90-windows.amd64).

For Modifiers, you can not edit the "Name" of the Modifier which was added to the original file.
And the "Name" of the newly added Modifier is editable. These are as expected.

As I said, you should not be able to add new shaderfx to an override currently, those will be lost on save/reload anyway...

Working of preventing adding those on overrides for now (again, this feature will be added once we have fixed issues in underlying system).
