For the 'coagulate' part, if you want the lights to move to the centre, you
can do a linear interpolate between the current point positions and the
central point ('pointer' in your ICE set up?). The blend value will give a
nice controllable attraction that should move into a round blurry shape.
Blend can obviously also accept inputs so you could do a distance to null
test or something.If you want a pure circle you could create a hidden cylinder, get closest location and use that to define the point position (you could then apply randomize to the positions to make it look 'fuzzy'). I'm a bit unclear on exactly what you're trying for but maybe that helps? On 6 November 2014 16:43, Byron Nash <[email protected]> wrote: > I seem to have it working.
