Played around with a random flame I'd saved, adding and tweaking a few things started getting some nice shapes out of it. As is usual with these things, that spread, and more things tweaked, and eventually had a bunch of nice looking flames. Too many to post at the Sanctuary facebook group. So here we are, have fun, please tweak and share your tweaks. Remember to link back here so others can try this out too.
Oh.. why nostromo ? well.. fans of the movie Alien will know. Other than that.. shrugs shoulders.
