Projector (Blob Shadow) does not work properly

Hi!

I have a problem with the projectors, even with the blob shadow from the standard asset pack. everytime the projector area hits an object (like a plane, for example) - the WHOLE object get´s the “blob” projected on it.

i´ve added two screenshots to make clear what i mean.
shouldn´t it be possible to limit the area where the blob gets projected?

solved it on my own.

if anyone else has this problem:
my fault was that i´ve imported the blob-projector from an older unity version.
when i´ve used the projector from the standardAssets of Unity5 everthing worked!
