Short description of error
It's looks like dependency cycle issue, but i don't find this type errors in terminal.

When I enable one object in viewport/render, it disables subsurf modifier from other one.
Both objects are linked from other different files, object this that subsurf modifier linked indirectly from same file, but from different scene.
Proxy armatures have dependencies via Child of constraint. One armature was removed in case of minimum size. When i try to make an object with this constraint, issue fixes.

Exact steps for others to reproduce the error

unpack zip file, open scenes/10/10-3.blend
test.zip
enable / disable "son complite" object. I will see, that object "car" will change shape
You can test same issue in render.
Enable "son complite" and "Cube" now subsurf modifier is active

@mont29 any idea what is going on?

No I don’t, and this not exactly a 'simple' file, there are hundreds of objects there, with bunch of complicated relations… Please try to reproduce the same issue with a pair of cubes, rigs, and lib files. Otherwise it will take hours just to understand what is supposed to happen here.
And please give a clear description of the relations between the problematic objects, too.

I fail to make a more simplified example

@mont29 Both Brecht and I took a quick look at this and we can't either figure out a way to simplify it.
Sure we could make the linked geometry simple. But it doesn't seem like it is the mesh complexity that is causing this.

that seems to be a very weird corner case then, and diving into it is gonna take ages, so setting to low prio for now.

I just had a look at the .blend files, and I really don't believe it's not possible to make this simpler. I can easily remove many objects, bones, drivers, keyframes, .. in the linked files while still reproducing the problem.

So please, simplify the file.

interesting... I can't remove some data... I think i should make an new report for that...

Michael Soluyanov commented

2019-07-02 17:19:45 +02:00

simplified as much I can:

test1.zip

Some data can't be removed because of https://developer.blender.org/T66345 Then I try to copy paste armature to new file, bug doesn't reproduce

The files has indeed been stripped down further, but I guess it is up to @mont29 to decide what to do now.

Am definitively not going to to spend more time on this. This is a weird mix of linked stuff, using regular subsurf modifier and Cycles subdiv one (which is not supposed to happen, it's either one or the other). Thing is, Cycles subdiv is tagged as experimental, I guess there is something badly handled here in linked data case? The way it's replacing actual modifier is weird and fragile anyway.

That's not really my area either, so if other devs want to have a look, they are welcome. ;)

Apart from the errors, there are cameras in different files that don't contribute to the issue, extra windows and workspaces that are not relevant, and I'm fairly sure there is more that can be removed. This is not a file we can use to debug this issue.

@crantisz we usually close reports after a week without reply if information/action was requested. You've just submitted some patches, so I'll assume this was just an oversight and leave it at a friendly poke for now :)
What was requested is that you try to remove any additional data from the .blend file that is not needed to reproduce the issue. Remove all irrelevant workspaces, windows, cameras etc. That may be hugely helpful to pinpoint the issue.

As I said, I failed to make example from scratch. I think this issue produced by early beta versions of 2.80 and can't be reproduced from newer versions. So maybe it can be closed as invalid?
