Maya 2017 Vray "Bifrost options" attributes

[scorpes]

I don't see a particle at all if I convert 2 vraymesh. The filesize of the vrmesh is big so that's good. Could you explain more in detail, how this process goes? Do you export bif2prt in default settings? and ply2vrmesh i did set a -pointSize but I don't see any particles. And how can I extract the particle density from the vrmesh?

Convert and load. That is the process All the channels are available via krakatoa

About combining channels - have no idea.

Yes, found the particles, it was idd working but the scale was 100 times larger. But can't find a way to plug the particle density in the opacity of a material. Tried particleSampler info. Hope Chaosgroup can find a way

Btw - you can try to use vdb for maya to export bif grid density param to somewhere in vray. Just not sure it will work, but I think it is possible. Maybe

is it possible now to access bifrost attributes like density or vorticity with vrayusercolor?
What's the best way to render bifrost foam with vray?

edit: Just to clarify, I want to render Bifrost Foam directly with vray StandardMaterial attached, but control the Opacity of particles with the Bifrost density attribute.
But I am not able to access it with vrayUser Nodes...

Would be quite urgent to know if it's possible with vray, as there is no documentation or tutorial online about Foam.
