LazyDodo (LazyDodo) triaged T52814: Alembic export with fluid simulation (resolution 250) causes Blender to close down with no errors as Confirmed priority.

baking took forever, and i needed the debug heap (asan will probably catch it on linux) to trigger the issue but here's a stackdump

Sorry for late... my previous answer was more for Kevin, and pipe details.
Here a simple alembic with some extra attr from maya. 'AnotherAttr' 'GuerillaTags'.

If i can send you more complex alembic i will do it soon.

Thanks a lot.

@Sybren A. Stüvel (sybren) In my older message there is a simple alembic with non-standard data, it come from maya. Tell me if you want more exemples.

Such custom properties aren't supported by Blender. This means that this isn't a bug report, but a feature request. We may implement this at some point, but not sure when we have time to work on it. A few simple example files do help, so thanks @colin (col-one) for providing one.

I've uploaded a blend file, you'll need to bake out the simulation before trying to export it as an Alembic file to see the issue.

You would need to create a fluid sim with a resolution of 240. I could get it to export OK with a resolution of 200 and dropping the number of frames from 200 to 50 in the animation.

Looking at the changelog for 2.79, Alembic Instances were never supported by Blender. I have support for this in a branch as work-in-progress, but it won't be part of 2.79.

I tested again today, using RC2 hash 7b397cd with Houdini FX Apprentice Version 16.0.671, and Alembic Vertex Color is still not transferring. Animation works, but no vertex color, confirmed still an issue.

Try either 2.79 Release Candidate 2 or today's daily build. If you pick a daily build, please also report the full filename of the downloaded file, so we know which platform, nr of bits, and the git hash of that particular version.

Master James (MasterJames) added a comment to T51195: Alembic targets for April 2017.

I have a single frame (#242) 100 MB Alembic abc exported from Houdini that crashes Blender 2.7.8c trying to import. Is anyone interested in getting this file and using it to debug this seemingly broken blender importer?
Where or how can I submit this bug report with file?
I don't really care about anything in the file.
Is there some guidelines for exporting alembic files from Houdini 16 that I'm missing? Like Dos & Don'ts. Thing is you really need some of the per vertex color stuff, because that can't be reconstructed from the poly-soup.
I've not used it much just testing at this point.
Should I try waiting for or the latest dev version?

I can confirm as for August 2017, no vertex color is exported with Alembic and kind of wish the vertex color can be baked for every frame. I tried using Sverchok, didn't work.

Try passing as_background_job=False to the operator call. That'll import the files sequentially, which should solve your issue.
