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

Hi kariomart,

No, it should not be needed at all. It should work. Please have a look below.

I have filled out a report and hope it will improve.

I had to stop last night at midnight, as we had our first meeting at 7 am (L.A. time). Now, I try to catch up after a busy, long day.

I explored your file a little bit more. So, here is my suggestion: it might render longer, but it needs a higher Sample radius for this file.

Try "eight" as the start value and measure in the Picture Viewer (CMD+Right mouse down) with the Alpha in the view.

That should work; if not, "ten" seems stable. I have not tested the whole file; I have only a laptop here as the fastest machine.

Sorry for all the waiting time.

My best wishes for your project

Hi diamond-childhood,

Here is a baked (not exported) Alembic. Object Manager> Object> Bake As Alembic.
Select the xpOpenVDMesher and its Vertex maps (activated in xpOpenVDMesher> General> Tabs: see image).

The baked object has the path to the abc in it.

In Redshift 3D, use the RS Render Tag and enable Motion Blur.
(Use Deformed Motion Blur in the RS Render Settings)

I have not included the Content Browser HDRI file; you must replace it.

The Motion Blur is set slightly over the top to make a point.

It does not work in any render preview or final render options, e.g., Picture Viewer.

All the best
