Christophe Leyder (shotalot) added a comment to T50725: Alembic export doesn't take 'Custom Properties', as alembic non-standard data..

Any news on this? This is a big one in terms of alembic for studios considering using it in thier pipeline, I will be more than willing to supply production example files in email, this will be for alembics exported from houdini specifically.

Bastien Montagne (mont29) closed T51820: Alembic sequence Crash as Resolved.

@Thomas Volkmann (knekke) please do not re-open old reports, even if issue seems similar, it is quiet likely to be something different, so new report is *always* the way to go (you can easily link new one back to an older one if needed, of course). Plus, it makes things simpler to track down (a report that is fixed, then mark as not fixed, then fixed again… becomes confusing).

Thomas Volkmann (knekke) reopened T51820: Alembic sequence Crash as "Open".

I have problems again with alembic sequences in 2.8. The sample files further up are crashing too...

Santeri Holm (Santerho) added a comment to T56792: Alembic doesn't export custom normals correctly.

This bug still seems to exist and is really getting in the way of our pipeline.
I did some digging and seems like blenders vertex normals are exported to point normals

It's best to create a new bug report, with all the required information and .blend / .abc file to reproduce the issue.

Irfan Celik (irfan) added a comment to T53745: Blender writes .abc color information wrong.

Could someone test this again in Maya?
I dont seem to get any vertex color info into Maya here even though re importing the abc back into blender does work.
Tested it myself here using the daily builds of blender 2.8, official 2.79 and daily 2.79.

Sybren A. Stüvel (sybren) added a comment to T60503: Curves to Alembic problems.

The curve loses its Geometry settings. In the example file the curves have depth and a full Fill Mode to them but once imported they switch back to the default settings of newly created curves.
The curve type is switched to paths instead of bezier.

Julien Kaspar (JulienKaspar) added a comment to T60503: Curves to Alembic problems.

I think the best solution for the studio right now would be to have the option to export curves as meshes like already mentioned here: T51311

MarkScene.ABC is hardly a minimal test file, it has over 5000 objects in it. Also, there are objects named ?????????#56_002, which to me indicates that there are more things wrong with this file.

This is more complicated than it needs to be, there is no need for UV hashing if we are going to compare them directly.

@Sybren A. Stüvel (sybren), could you look into this? I have neither the Blender sources nor my Alembic files on my computer at the moment. Overall, apart from some style issues it looks good to me.
