Sorry for reopening however I would like this to be reconsidered. The active camera 'should' have special privileges which evaluate it regardless of whether it is visible or not, as it causes much artist confusion to when the camera 'should' be animated but is not.

Not a bug. You have disabled evaluation of the objects in that collection. So this is the correct behavior.

We fixed a similar bug at some point after this report, appears to be fixed now.

Needed to apply manually, and forgot to mention the revision in the comment.
Committed as rB76437b903de.

The only alternative that comes to mind would be to improve the solve_cycles function so that the resulting graphs are ensured to perform orderly cleanup. But adding extra relations seems like a more clean/maintainable solution.

I don't have a better local solution.

For that issue, see T62094: Unable to insert a hide_viewport keyframe via the UI.

@Brecht Van Lommel (brecht), do you feel strong here? Can't think of a better solution than to introduce more relations.

@Dalai Felinto (dfelinto), this change has nothing to do with solving cycles, it just makes blender to not crash when there is a cycle.
From reading the patch it seems fine to me.

Likewise just tried object visibility keyframing in latest build as of today (Mac) and still no option to keyframe or add drivers to object viewport visibility (eye icon in outliner). This is quite a crucial feature for me to start migrating my main project to 2.80

The patch (updated on - P934) seems to work (no crashes).
There are tons of dependency Cycles errors though (full list P935):

'OBArmature.Mario.POSE_IK_SOLVER()' depends on 'OBArmature.Mario.Spine.Bendy.BONE_READY()' through 'IK Chain Parent'

More than a week without reply or activity. Due to the policy of the tracker archiving for until required info/data are provided.

Crashes also after referencing a scene property from another scene (in a single file):

Hello, I am facing the same problem.
Can someone give an example or a step by step guide of how to key visibility on instanced collection or object? (with the latest build of blender 2.80)

This seems resolved for me.

Currently only objects visibility is animated.

Hi Guys,

@Sergey Sharybin (sergey) : this will make me the happiest man :)
I'll test it in the next build.
Thanks a lot.

@Brecht Van Lommel (brecht), @Sylvain (Micool), fixed it now.

@Sylvain (Micool), please create a new bug report about that.

On blender-2.80-e795dd4a20a1-win64

Committed quite some fixes in various related ares and this report is supposed to be fixed now! The minimal revision required is rB846d265a06e.

Weird. Was looking for quite some time =\ Thanks!

There will be more optimizations.

@Sergey Sharybin (sergey): file was there in the report (made this more visible now...)

Please always attach .blend file which demonstrates the issue.

Confirmed.
At the moment my demo scene with some modifiers is at 5 fps in version 2.8.
In v2.79 its faster and runs at about 8 fps.

Thank you for your effort. It works now.

@Sergey Sharybin (sergey), can you review this?

This appears to be solved in the latest builds.

@Campbell Barton (campbellbarton) : is this OK to stay on your desk?

AddressSanitizer: heap-use-after-free P911

Can reproduce here

Also I don't know if I should write here or create another task, but I can't even insert keyframe on viewport visibility, while I can insert one for render visibility. It will show an error as shown in the screenshot:

I've just discovered this problem. I don't really understand the script workaround, but I know it's something with the internal code not updating. Because if I move a keyframe of Disable Render channel from the object, it will be updated, but then stays like the last render until I move any keyframe of Disable Render channel again.

There were few things wrong in dependency graph and instancing code. Should be fixed now. Thanks for the report, closing.
