Hi,

Anyone know if its possible to use the alpha channel or non-transparent area of an objects material to target for `find-target` or `speed by surface` operators?

What i have is a plane with a video mapped onto it and i want particles to `swarm` just the part of the plane that is not transparent..

Thanks in advance,
DavidGallagher.
