Hi,

i am loading movies into a container that is masked off using setMask(), however when i apply a filter (blur) the blur is visible outside the masked area… anyone know a fix?

cheers,  
Gareth

roaden the mask size according to the blur amount your applying.  
For instance for a 5 pixel blur ( on x & y) make ur mask MovieClip \_height and \_width bigger by 5 pixels (just pay attention to the registration point of the MovieClip to get a centered resize )

Hope it helps 🙂

Hi,

thanks for that, but does this not defeat the point of a masked area??
