Hi, got some weird artifacts recently in some interior renders on C5 RC2...
I'm not sure if they're related, but before the render I got some Corona errors telling me about some NaN... sorry, but I didn't save the error log or report the bug as requested.
However, please see attached screenshots and let me know if you can tell whats happening... Thanks!
(P.S. I tried turning off adaptive light solver, but it did not help).
