VDBfromparticles creates a hollow fog volume

[mikethomson]

Hi there,

I'm trying to create a thick smoke trail, but when I convert the particles into a fog vdb, I get more of a hollow look. I kind of need 'fill interior'  like vdbfrompolygons. I did a search and found kind of a solution using volumerasterisepoints, but I can't figure out how to pass custom attributes to the vdb (ageNorm for example)

If I stick with vdbfromparticles, how do I fill the interior?
or

If I go with volumerasterisepoints, how can I pass point attributes to the vdb and the shader?

or

Is there some other solution that I'm missing?

Thanks,

-Mike

This first image is how I filled the trail volume with volumerasterizepoints, but I can't figure out how to pass attributes to the shader

Have you tried just multiplying up the density value after the vdbfromparticles? Just put down a volume wrangle and do something like:

@density*=10;
