These breakable FX where totally collaborative, One co-worker did the 3D models and another defined the VFX style for pandemonium so by the time I got to finish them up I had some awesome materiel to pull from! These are probably some of the coolest breakables I got to work on, and its totally because I got to build on top of an already awesome foundation!
When they are destroyed they evaporate into dust and mist, as though they were barely clinging to the corporeal realm. I was thinking of how paper burns when its being carried up in the hot air of a camp fire and how the materials should look like they were getting eaten away as they drift though the air. If you played the expansion I hope you remember them.
