V-Ray - Metaballs and Maya 2017

[Irongraft]

Hi guys,
I'm new in this forum. I've bought a license of V-Ray for Maya and tried to make a spere with a particle system emitted from its surface.
I've associated a VRay Metaball to the particle system and on Viewport 2.0 I can see the particles on the surface (img1 below).
However, when I render (img2 below), the particle system (and the Metaball) are not there.

Can you help me understand how to render correctlya and what's wrong here?
Thanks

Hi and welcome,

The second link seems to be broken, could you upload that again, please? You can also try attaching the images directly to your post.
See if our documentation on vrayMetaballs is going to be help you https://docs.chaosgroup.com/display/...C+VRayMetaball
and let us know if you still need more help.
