Sybren A. Stüvel (sybren) added a comment to T69308: Unable to read back in external baked physics cache.

I did some digging, and it turns out that ptcache_read() reads the correct number of points. It's ptcache_particle_read() that's rejecting the points because psys->totpart is set to a low number (i.e. to the number of points you're seeing). Somehow it's not getting the total number of points from the pointcache. This could be due to the fact that the info file (i.e. the bphys file for frame 0) isn't written to disk, but I'm too unfamiliar with how the code is supposed to work.

Sybren A. Stüvel (sybren) added a comment to T69191: Alembic Import: Visibility.

This is indeed not a bug, it's simply a property that's written to Alembic and that's not read by Blender. Alembic is quite bad in this respect, in that there is no well-documented open standard in which such properties are defined. I'd be very happy if you can prove me wrong on this one.

@Carl Schwan (carlschwan) That's great news. I looked at https://phabricator.kde.org/T8449, and it seems that your goals are in line with ours. I'd love to see 2FA in there (I have a Yubikey myself that I use whenever possible); we just didn't have the time to implement that. Some more security improvements (like limiting nr of failed logins, monitoring API calls, etc) would also be very welcome. We'd definitely be interested in any improvements that the KDE project can make.

Hi.
While this is a nice improvement of add-on filtering, it makes it slightly more difficult to search for a "disabled add-on" within the list of add-ons (since now, the disabled add-ons are listed with the activated ones).
Could it be possible to have two radio buttons for "Enabled Add-ons Only" and "Disabled Add-ons Only".

@Chris Rydalch (goldleaf) Can you check whether this is still an issue with a daily build of Blender? I don't have Houdini here, so I can't check for myself. I tried exporting a NURBS surface and opening in Gaffer, and that doesn't show anything. However, I don't even know whether Gaffer even supports loading NURBS surfaces...
