Black Streaks in ProRender

Hi All,

I’m rendering a mall in C4D R20, but ProRender is rendering with some unpleasant black streaks. Please see attached.

The streaks are shown inline, but across different and independent geometry (see the ground floor and right 1st/2nd floor).

As the camera moves, the streaks stay with the camera view and move over the geometry (like kind of a reflection, but still happens with no material applied).

This is especially noticeable in the angled streaks that you can see on the right side of the corridor/railing across all floors.

This doesn’t happen with Physical/Arnold, but I’m on a Mac, and this scene takes much longer to render with my CPU on them.

This is the first time I use ProRender, any suggestions?

Thanks
