Now in the video im using a pre shatterd file/object which works much butter, but in a atempt to make the .hipnc file independant I replaced the file with a box/shatter node.
It doesn't look as cool but the basic premisis is the same. Using a point SOP, setting colors on the primitives with a dopfield() reading Impact data from the DOP network, then a group SOP controling where the particles emit from.
