Sacadas stuff are VOBs. You can modify the materials and save them yourself or modify the vobs - the spheres more or less (try it with some metablobs maybe) - and save the results as vob again. As an example, look at the materials Sacada has used/done. Gives you a good expample how fire materials are done. BTW, have you done a search in the freestuff zone here for fire? Loooong time ago there were some fire materials for Vue 4 available. Result of a monthly contest when i remember it right. Maybe gone forever, who knows.
