export alembic mesh have some problem
#1
This is a problem when exporting the same result to alembic source.
(Please check the attached image.)


If you just use the export op, it is not included even though you set map ch2.

However, when I max_fileMenu>export this through tymesher, ch2 is filled.

However, in both cases, no velocity channel was found.
I don't know anything else, but I hope the velocity channel can be added as soon as possible.
Thank you.

ps : The particles in this scene are those that are created and erased at runtime. Note that..

Checking with vrayProcxy, velocity is included.
I was able to render the velocity pass without any problems.

But it's weird. Alembic doesn't include velocity.
How did I render the velocity pass in the meantime.
Or is there another way I don't know? How to render the velocity pass using the alembic mesh.
If you have any tips, please let me know.
Thank you.

Can you please attach a simple scene file, with your tyFlow and Export Particles operator included? That way I can test and reproduce the exact issue you're describing.
