IR and VfB/PV render differently

Render in PV and with IR. Different results, IR renders wrongly, PV and VFB correctly.
Ok, it’s almost a hack with the correction deformer and the vertex map, but well …

Needs R20+

Corona Beta 2, Window 10, C4D R20

Well, short correction:
To make the IR render wrongly, press play in the timeline and start IR.
If you stop the playback and restart IR, it renders correctly, too.

Thanks for the file Mike, I’ll try and have a look at this today at some point.
