forestpack areas - boundary checking - edge does render AO of the cuttet object

hello,
vray 3-60-04 shows the AO of the edge cuttet object.
so far it is all right, the objects get cut at the edge, but its wrong that i see the AO of the rest of the object that got cut away

problem of FP 5-4-0 or Vray?


you need to activate work with transparency on vraydirt material

big thanks, that did the trick !
