Hi, I was wondering if there is any possible way to add a particle ID to a vellum fluid?
The vellum solver doesn't give the option, and I tried to do it manually but I couldn't figger out how.

Any body that can help me solve this issue?

I'll second this ... I just realized that I can't find an option to add IDs to vellum grains anywhere?

Thanks in advance,
Tim

add the ID to the source?
