Whats the prefered way to cache particles for vray render?

Whats the best way to cache particles in order to render them with vray? I tried .vdb but they dont render in volume grid. I tried alembic but importing an abc cache doesnt work with sequences. 

 

How should i go about it?

The lack of vray compability drives me mad :)!

 

all the best

Daniel

Use the procedurals that Vray gives you. You should be able to grab alembics and render particles, strands, geo with it. 

 

Vrayvolumegrid should work with .vdb 

 

Both of these options worked for me. Do you have any repro scene where this do not work?

Hi, i did'nt understand you there! The procedurals, could you specify it more? I hooked up my particles to a file_cache node and cached particles as alembic sequence but i can't seam to bring the sequence back into maya only single files.

 

Is there a better way/format/method to cache the particle sim and make it renderable with vray?

Maya, unfortunately, does not support importing animated point clouds through Alembic.

 

Like @sepu6 said, your renderer should be able to render points stored as either Alembic or OpenVDB point caches. Naturally, we cannot help you with how to use VRay here on the Bifrost forum.

What I mean is using the Vray proxy, if you import using the Vray proxy you can read points, strands, and geo. It reads the attributes that Bifrost gives you so you can use them to shade for example. 
To render volumes use the volume grid, Which should give you access to the different fields.
