Invalid curves from exported alembic cache
Open, LowPublic

Short description of error
Exported alembic cache contains curves with invalid vertex counts

Exact steps for others to reproduce the error
I downloaded the rocket/launchpad model from blendswap (http://www.blendswap.com/blends/view/69355), and exported the scene as an alembic cache.

The cache imports into Houdini just fine, but when rendering, it crashed. When I submitted a bug to SideFX, they indicated the curves being generated have invalid vertex counts, and are corrupt.

Thanks!

Kévin Dietrich (kevindietrich) triaged this task as "Low" priority.

Sounds like more or less the same issue as in T49114. In any case fixing this without proper knowledge of how other software expects curve data to be written will require a bit of trial and error, so setting priority to Low.

@Chris Rydalch (goldleaf), for reference, if there is more information about the crash there, do you have a link to the Houdini bug report? (Or a screenshot if private.)
