Struggling with Steam

[kmaas]

Trying to make a jet of steam shooting out of a pipe with HyperVoxels and having some trouble. I can't seem to get it to look right. I'm trying to get it to look like real steam, where it would be clear when it comes out, then turns into a semi-transparent white billowing cloud, then dissolves into the air. Anyone have any pointers?
