I suspect that solving this properly requires T69046.

@Sybren A. Stüvel (sybren): will tag as Known Issue (or is Design preferred?)

Hello, i just found a workaround for anyone needing this feature, I'm being able to render curves exported from houdini, im using the alembic as input in geonodes and then rendering the geo node object, but i had a few crashes but i could render a frame sequences with this setup

@nizar amous (zinar) thanks for the solution, however, as of version 3.0.0 2021-11-08 this workaround is no longer working. are there any other possible workarounds anyone is aware of? thanks!

I was having the same problem and the solution I found was export it from blender as alembic and check the option "Curves as Mesh" and reimported it and working nice!
Hope someone can found this solution too!

Thanks @Andreu Pellisa (andre1) this is good to know (although in my case I'm exporting from Houdini so this is not an option).

uuuh, really hope this issue is not being forgotten,, unfortunately I have to bring objects back and forth from and to Maya (I know, I'm a traiter, hahaha) and with this limitation, unfortunately I can't use blender in certain cases

hey, when I try to export curve as mesh, it only exports the vertices and now edge lines. Really need this to get working, would appreciate any help big time

Is this really forgotten for over four years?
This is a huge problem

I very much agree on this. Blender undergoes this massive growth, which is plane amazing and thankfully due to it's versatility there is always a workaround for pretty much anything. In case of alembic curves, I cached them out as pc2 and added thickness via geometry nodes post mesh cache modifier. However fundamentals like this maybe shouldn't be left behind imho

A new implementation of curves objects is currently ongoing, which will among other things allow to properly support Alembic I/O. The current plan is to get this ready for Blender 3.2.

As a teaser, here's a final render with the new implementation of the file in this report:

That is amazing news, thank you very much for the update

any updates on this? any branch build to try it on?

There is no branch for it, but if you would like to try you can apply the following patches in order :

• D14484: Cleanup: Alembic, use a structure to pass parameters
• D11591: Alembic: import arbitrary attributes
• D11592: Alembic/USD: use geometry sets to import data

Specific details are in the patches descriptions.

yeah I barely can use python lol, I will wait till the 3 patches get merged into master or a branch of their own

I can confirm 22 April 2022, the Alembic Curve bake out still does not animate or moving forward during render using Blender 3.1.2 and 3.2. Will wait for few days / next update....

There is no need to test, you can check the status of D11592: Alembic/USD: use geometry sets to import data, once this is closed and marked as committed, then you can test.

Hey for those looking for a hacky workaround to get animated cuves in to Blender from a software package such as Houdini as long as D11592 is not merged yet, checkout this thread: how-to-render-alembic-curves-hairs-from-houdini-with-this-hack
