Hi Lennart,

The Alembic Node in Houdini needs the Motion Blur enabled. This allows for the settings of subframes and what Shutter settings you like to have.

Please render the rough test scene in the picture viewer. While the Redshift is set to "Transformation Steps".

Of course, if the animation only has linear interpolation among all keyframes, substeps will not fix that. You need to explore that in Houdini.

All the best
