wierd white shadows affecting alpha pass with VRAY

[Hwagner]

i am rendering this view, the gras seems to be casting a weird white shadow. i chech the alpha and it is affecting it aswell. WTF is going on here? i have never seen this before and cant seem to find an answer. there is a plane under the grass and a curb right against it, there is no reason for this issue. i hope someone can answer this for me. pulling a late night trying to get this finished.

max 2016

well. i found a solution, i increased teansparency samples in the global switches and the issue went away. something so simple and hours lost.

i guess it is an itoosoft plugin issue. the solution is to reduce the distribution size in forest pro, which isnt really a solution, especially when using the edge cleanup mode,  or increase transparency samples in the global vray switches.
