Krakatoa ghost arm dissolve from Hugh Johnson on Vimeo.

Originally done as some R & D on a ghost show for the BBC. One of the characters was going to dissolve and reappear using this type of effect.  The show didn’t get to pilot though, and this was as far as I took the testing.

Rendered with the excellent Krakatoa point renderer.  I did this a while ago, but I think there’s about 1 million particle flow particles, each one receives and casts shadows.
