Cinema 4d+Alpha v4 | INTERACTIVE RENDER

[rodut1112]

There is a bug (i think ) in the v4 interactive render. I scattered some grass with SurfaceSpread by laubwerk , and in the C4d Picture Viewer everything is ok, but in the interactive viewer there is some extra grass in places where i didn`t intend to scatter. Also there is a HDRI lighting bug.
 This happens on C4d R16+Alpha V4

I can confirm some strange behaviour with IR. It renders with geometry artefacts.
Image on the right is rendered in picture viewer, the left on in IR. There seems to be missing part of the geometry on the floor.

cheers
