Welcome to Librarium Online!
So, in the new VC book it's possible to upgrade a vampire to have the 'Ethereal' rule. Since turning to mist is a pretty common vampire 'ability' in a lot of lores, this seems like a good modelling opportunity! Anybody have any ideas on how the heck to model mist?
Best I can suggest is finding some cottonballs and tearing them apart a little. Not very reliable once you store it away, though, since it'll get packed down. Plus they're hard to glue in place. However, it's the closest to smoke/mist any model has.
One idea, which would require more skill and patients (spelling?!) then anything else, is to use various sheets of plexy glass.
use a good thickness, and layer it many times, since it will be layered several times, you should use a plexy glass that is still kind of clear, but still kind of whitish tone.
Afterwords, using several cutting tools, of various shapes and sizes. to cut a sort of ball into it, so that all edges are jagged and random shapped. Using a tool to melt said edges afterwords might work to keep the 'smooth' feeling of random mist forming so to speak.
Afterwords, you might try dry brushing very watered down greys/blacks/whites to the edges in random spots.
If this works, all edges should be randomly smooth and melted together, and you should be able to sort of see through it, but it should still be very white... with random hilights here and there.
This could take a lot of work, more then it is worth, and might not even work, but it is something that could turn out really well if done right.
Another idea, if you cant get the 'burning, or warming' part to work, try using water effects to smooth out all the random bits....
I dont know if I am illustrating my idea well enough using words, but alas, I am at work, and I dont have any picture programs to draw you a very bad picture, as I am terrible with my drawing skilz.
Hope this helps
Casting some bits in clear resin might be an idea too. Then you could add a drop or two of white acrylic to the middle of the mold and give it a stir or two with a toothpick.
