Hourglass Effect Help

[PortalPyro98]

I'm wondering what would be the best way of approaching an hourglass effect where the sand goes upwards. The hourglass has to be taken out of Houdini and into Maya and is going to be placed into a scene ontop of a table.

Any help with how you would tackle this kind of effect.

One way of achieving this would be , with grains , negative force for flowing down and positve force for upward motion ,

or cache the downward flow , rotate it 180  

file attached its a quick mock up , so you can model the hour glass to suit your needs,

 

and to export it to maya , copy spheres to these points export as alembic

Found out a better way of importing particles into Maya from Houdini. Instead of copying spheres to points you can download the import_Bgeo_Maya from Orbolt and you can use the Houdini Engine plugin in Maya and load up this Import file. In this object you can open up the Bgeo file and select output hidden object.
