I tried this a way ago, too ...

What I did, was to create the object as an isosurface ...

one complete black object with threshold 0
and anotherone with threshold 0.01 and emitting media

what I neded to do was also to increase the accuracy of iso and
a lot of time ...

The thing is, that the iso gives you more flexibility for design...
