For a current project i'm trying to make a "pulse" or a "burst" of light.
an Emitter in space creates a small globe which scale bigger and bigger.
The globe itself should be almost invisible, but the intersecting parts between globe an remaining environment should light up and glowing.
The environment is dark, it should light up following the "intersection", staying light for a short while an become dark until the next "pulse" moves by.
A little bit like the patronus in Harry Potter http://www.youtube.com/watch?v=Azyhq-gwk-M (at 0:23-0:31 )
There is no footage in the Project, everything is complete CG.
Main work is done Maya and i hope there is a way to do this.
I dont know if this is post work or not. It would be great if someone has an idea or expierience with this type of effect.
