@Lukas Ziechmann (bl_cat): note this isnt commited to master yet (want to check on an issue in 2.8 first so the merge would go smooth ...)
reg. T54397: surface deform is now ported as well, but changes can happen later as well [just need proper handling of 2.79 vs. 2.8], lets stick to that report and continue discussion there

*wow* - getting back from work to find the bug I reported yesterday to be already fixed for 2.79. Thank you so much @Philipp Oeser (lichtwerk)! Regarding my other bug report: T54397 , do you think I should CC a 2.8-developers directly as the surface-deform modifier isn't ported over to 2.8 yet or would that be considered annoying/ unhelpful? I don't know the policy here and I don't want to clutter their chat with unimportant messages. Thanks again for your time and effort!

lattice was already ported (see T54737), so this will need to go into 2.8 with minor tweaks separately

this probably wont merge into 2.8 cleanly [DerivedMesh → Mesh conversion], I guess I'll have to make another version for 2.8 as well [which should only be minimal massage].

Sergey Sharybin (sergey) closed T53251: Armature modifier on hidden objects as Archived.

Depsgraph indeed only takes layers into account. This way it's cheap to see if some object from hidden layer affects something currently visible. In Blender 2.8 we are switching to collections visibility instead of object visibility. This part is still being worked on, so need some work to make depsgraph aware of that once rest of design is locked down.

Fri, Apr 27, 1:31 PM · Modifiers, Animation, BF Blender
Philipp Oeser (lichtwerk) assigned T53251: Armature modifier on hidden objects to Sergey Sharybin (sergey).

At a quick glance at the code, dependency graph is only aware of layers, not object visibilities at all.
This is not limited to the Armature modifier, seems all modifiers evaluated (e.g. on frame change)
(Above difference in fps between visible vs. hidden is probably drawing code etc, not modifier evaluation).
So in that case, I would think this is a (somewhat known) limitation to the depsgraph?

Philipp Oeser (lichtwerk) added a comment to T53251: Armature modifier on hidden objects.

While it is very well possible that hidden objects need to be evaluated (think of something shrinkwrapped to a hidden deformed object - you would want the deformations to be evaluated), it doesnt have to be so (agree, it would make sense to skip evaluation in that case).

Campbell Barton (campbellbarton) added a comment to T54024: BMesh boolean fails when edge is co-planar to face (under some circumstances).

mathieu menuet (bliblubli) added a comment to T54024: BMesh boolean fails when edge is co-planar to face (under some circumstances).

Addons relying on carve modifier are not working in master like this one https://blenderartists.org/forum/showthread.php?409837-Destructive-Extrude-BETA/page9 and the results of bmesh are not yet there in some cases (like overlapping/coplanar edges/faces).
I think it was a very good idea to keep only one version of the boolean modifier and bmesh is really fast, but it should offer as much as the old combination. Or is the plan to only remove functionality in this case?

Just saw that "Shapekeys" of a target mesh have no effect in combination with the "Surface Deform"-modifier as well. This modifier really seems to overwrite any other transforms..
