Title: pass 50/ black dot/ black screen
Post by: koubankeo on 2019-02-18, 12:57:11

Hi,

I have a problem with a larger exterior scene. The black dots appear in pass 50. With bloom and glare turned on, the screen is black.

Do you know what it is???

Many thanks

That thread has all the information we have so far - these are NANs (Not A Number) pixels, which means there is an error somewhere with Corona, which we are investigating but haven't pinned down yet. It's an unusual situation as we've not seen NANs that only appear after a certain number of passes before (in either C4D, or Max), that I recall anyway - NANs are usually there from pass 1. So that makes it a complex issue to investigate - we are on the case, though!
