Have the same problem, here is a side by side basic test
Wed, Apr 17
Is there an alternative to that workflow? Because we use real world scales to be consistent with lighting and materials over live footages. How can we interchange hair between Alembics and still maintain real scales?

Tried to do that but it still breaks the hair
Applying scale is not supported. This changes the mesh data, which is replaced with the data from Alembic. Try creating an Empty, set it as the parent of the imported Alembic object, and scale the Empty.
Hi Atomic and Sybren,
Unsure if applying scale is supported for sequence caches. @Sybren A. Stüvel (sybren) any input on this?

I tried the Tree.abc file in Houdini 17.0 and it does not work. When I unpack the data, I can see that a 4 float vector is written, but that is wrong, it should be only a 3 float vector. Even when I promote (or wrangle) the data into an attribute @Cd, that the viewport expects, all the data is zero (i.e. black).
@Sybren A. Stüvel (sybren) ok, sorry not doing it before....should be done right now
@Libor Batek (lbatek) please put the description of the issue in this task, instead of hiding it in a ZIP file. Hiding it like this makes it invisible to the search engine, and makes it harder for developers to access as well.

Confirmed on first sight
(Looks like 2.79 has a similiar issue even)

Just edit the task description of the other task if you want to add your findings.

Yeah, Bastien. In my case, I found the solution with FBX export.
Note that FBX should also be able to export vertex color data?

Havent actually checked it, and it feels like swapping mesh datablocks in a framechange handler is not the best solution, but would it help getting the evaluated object?
Hi guys. Just found this bug in Blender. And searching brings me here.
I tried to export vertex color from Blender to Maya. Alembic the only format I found to have "vertex color".
And it's doesn't work. Maya can't see the color.
So why can't I fetch the mesh data block, from the .abc animation, in a frame change?
Shouldn't the Mesh Sequence Cache modifier correctly present the current mesh data block, to the API, for the frame it is displaying?
Why does the frame change code fail?

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.

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

So it's been a year since the last post in this thread. Still nothing? I really miss this feature.

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

I created one here https://developer.blender.org/T60977
It's best to create a new bug report, with all the required information and .blend / .abc file to reproduce the issue.
Jan 28 2019
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.

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.
