I recently starte getting massive artifact when viedw or rendering tree in iclone 6 where it wasn't doing it earlier. Here is a partial render

and it the full video render earlier (ithink iClone 5)

This only happens in videos with trees (i'm using the 2014 total blant bundle)
I have an nvidia gforce 970 runing in an aliein ware Area 51 computer. I have treid reinstalling the video drives but nothing changed.
Any ideas,
