Matching Motion Blur and holdout between Maya and Houdini Renders

[UpyopyoSky]

Hi everyone,

Our team is planning to render elements using both Maya and Houdini. Maya will handle most of the polygon assets and animated props, and Houdini will be responsible for FX elements such as particles, points, and volumes. (I understand that rendering everything in Solaris would be the safest approach, but for pipeline reasons we’re splitting tasks between the two.)

On the Houdini side, we’re planning to use Karma, either CPU or XPU, depending on the shot.

My question is: which render engine in Maya matches motion blur and holdouts most reliably with Karma?
At the moment, the main candidates are Arnold and Redshift.

If anyone has recommendations based on real production experience or R&D testing—especially motion blur consistency, and compositing accuracy—I’d really appreciate hearing your insights.

Thanks in advance!

Your best bet is either using Arnold or Redshift if you gonna use both, not Karma. With Arnold and RS you have plugins for both and for the most part you can match basically everything.
