Iray Renders - Darkening prior to completion

plaul2002

Hello,

 

Is anyone else having the problem?  Basically I run a render and its works fine for about five minutes then all of the sudden its completes and 50% to 90% of the render is black with a line going straight accross.  I runt he render 2-3 more times and then finally it render correctly.  No changes.  I have V. 4.12 on WIndows 10 with two GEForrce RTX 2080.  

Additonally, running a render and it starts fine looks to be a nice clear render then all the sudden BOOM adds noise and sets back the render 20 mins....renders more and boom sets it back again.  What the heck is going on?

 

Thank you for any help.

Might be solved I deleted some figures in the scene and that seemed to help.  Three figs and a bar scene and going to CPU.  I can't figure out how to get IRAY to just use my GEForce RTX 2080s.
