Quote - "but a plug-in for poser would be a great addition."

To What end??
What DW is releasing is Open VDB C++ libraries which allows animators to more easily create “volumetric” effects, such as smoke and other amorphous materials.

This will make it even easier for apps like SideFX Houdini to render huge Volumetric animated effects like the ones seen in big VFX films like "2012".

99% percent of the poser base renders stills

not hi-def VFX  animated shots that would like be sent out as  layered EXRs from Renderman or some other pro pipeline engine
( ie NOT firefly).

Cheers

 

Maybe something SM themselves can utilise when they rewrite Firefly with industry leading volumetrics ;-)

I think the Mozilla license the library has been released under would accommodate such a use?
