Yesterday

Demeter Dzadik (Mets) added a comment to T68740: Mask modifier slow when one of its properties is animated/driven.

I think an interesting idea would be to allow Custom Properties to be set to non-animatable.

Peeter Maimik (z01ks) added a comment to T60695: Optimized per-datablock global undo.

Just wondering if it's possible to estimate whether there will be global undo performance improvements to be expected in 2.82 and which bcon phase? Thanks!

Bastien Montagne (mont29) added a comment to T70709: Switch Blender task scheduler to use TBB.

I hope that this partial switch to tbb does not bite us in some unexpected ways… would have rather switched entirely…

Sergey Sharybin (sergey) closed T68740: Mask modifier slow when one of its properties is animated/driven as Archived.

By adding animation to the modifier stack you effectively make it so the modifier stack depends on time (since animation depends on time, and modifier stack depends on animation).

Peter Fog (tintwotin) added a comment to T70529: Verify ffmpeg and other image and video libraries use optimal build flags.

These settings will enable hardware acceleration -hwaccel auto and this one -tune fastdecode will allow a much faster playback in Blender(going from 20 fps to 30 fps on my low spec computer) and this one will use all threads: -threads 0 I don't know which ones are enabled in the Blender build of ffmpeg lib, but I know from testing alternative codecs for proxies, that these settings will make a difference in encoding/decoding speed(though some of them may be h.264 only).

Brecht Van Lommel (brecht) added a comment to T60695: Optimized per-datablock global undo.

That's a discussion better held elsewhere, this task is only about solving a specific performance issue in undo.

Nick Moutafis (sinokgr) added a comment to T60695: Optimized per-datablock global undo.

@Charlie Jolly (charlie) yeah, maybe but to be honest, personally I wouldn't change its default behaviour. It works as people expect. The only issue I think people have, is with the performance. That's my opinion at least.

Charlie Jolly (charlie) added a comment to T60695: Optimized per-datablock global undo.

@Nick Moutafis (sinokgr) I see your point but that might be better managed by using frames and groups

Nick Moutafis (sinokgr) added a comment to T60695: Optimized per-datablock global undo.

Nodes selection is very common to be stored in the undo and it is very useful in many cases, especially on huge scenes where they will be very slow to navigate and you may have had to manually select many objects and you might accidentally click somewhere that will lose your current selection.

Charlie Jolly (charlie) added a comment to T60695: Optimized per-datablock global undo.

Undo also stores unnecessary things. E.g. node selection is stored.

Demeter Dzadik (Mets) added a comment to T68740: Mask modifier slow when one of its properties is animated/driven.

(This affects playback performance at the studio! 👀)

Germano Cavalcante (mano-wii) assigned T68740: Mask modifier slow when one of its properties is animated/driven to Sergey Sharybin (sergey).

I can confirm.
I don't know if this is a known issue or maybe there really is some unnecessary update.

Casey Connor (clepsydrae) added a comment to T70432: Workbench animation renders are extremely slow (2.79: <25m, 2.80: 6-8 hours).

Thanks Germano! I will note that I don't know if it's necessarily a workbench issue (see 3:23pm comment: seems to be the same thing going on with eevee, partially related to color space transform, etc.)

Germano Cavalcante (mano-wii) updated subscribers of T70432: Workbench animation renders are extremely slow (2.79: <25m, 2.80: 6-8 hours).

Ok I can confirm as a regression.
@Casey Connor (clepsydrae), I hope you don't mind, but I edited the report description.
@Jeroen Bakker (jbakker), this involves workbench so it's your area as well.

Germano Cavalcante (mano-wii) reopened T70432: Workbench animation renders are extremely slow (2.79: <25m, 2.80: 6-8 hours) as "Open".

Face count by default makes more sense to me.

Alberto Velázquez (dcvertice) added a comment to T70358: Poor performance with QuadriFlow on high density meshes, eats RAM, and refuses to cancel when pressing Esc.

I don't see why don't use the face counts when Zremesher uses face count by default.

Kenn Nyström (Frozen_Death_Knight) added a comment to T70358: Poor performance with QuadriFlow on high density meshes, eats RAM, and refuses to cancel when pressing Esc.

I would say keep ratio as default, as Brecht already mentioned. QuadriFlow simply needs to get smarter and not overshoot the amount of quads it can produce. ZRemesher on average produces around 120-150k verts when used on a human looking model at max settings, which should be a decent goal to set for QuadriFlow. Trying to go beyond that will make it too taxing on pretty much any computer.

Like an artist I vote for face count, is the first thing that I do every time.
