Arnold not rendering X Particles Dynamic Objects

Hello. I am working on a project now using X Particles And Arnold. I am done with the simulation, cached and everything seems normal both int he viewport and IPR but when I try to render Arnold won't render the objects with dynamic tag. I am attaching screenshots and a sample video. Does anybody know why this happens?

Not sure, maybe some X-Particles settings are missing. Can you render with Standard or Physical to see if the simulation is correct there? If so, could you share the scene?

I'm also experiencing this. Did you find a solution?

No update on this, never received a repro. I can take a look if you can send me a scene.

I'd appreciate that — sorry for the slow reply. Here's an example scene I put together that shows the issue. This is with Cinema 4D R22 on a Mac.

It seems to be working if you convert the Sphere to a polygon object (Make Editable), but not as a primitive. I'll take a look if this can be fixed.

That did the trick, thank you. But yes, would be nice to see fixed.

On that note, I've also noticed that spheres in metaballs, which I believe must be primitives for the metaball to work properly, suffer from the same issue.

This should now be fixed in C4DtoA 3.1.0.2.

I'm experiencing the same thing, but I've just updated Arnold to 4.0.2 earlier today. I'm also unable to render X-Particles with motion blur in Arnold.


For what it's worth, I'm using R21 on a 2019 Mac Pro, running Big Sur (11.6.1).

Could you please send me a scene to take a look at?
