False shadow on pngs

hi, this is a 2d question

is it possible to do shadowing effect like here but lighter ?
i have plenty object to shadow at same time in a kind of false shadow ( 2D approach, layers approach) and i was asking myself if there was something else doable.
bluring (thxs to uncs power once again) will create helas to many renderers if i began to spread.

cheers ;-)

hi karistouf,
why you using Blur instead of DropShadow?
if i catch your question right - group all your objects you want to give shadows, make pass renderer and let it pass DropShadow
cheers and merry christmas,

damned ! never noticed it ! thx dimix, and a merry xmas ;-)
