Quote - If that is the mesh poking through there is 2 methods I am aware that might fix it.  Apply a slight displacement to the pool coping or increase your render subdivision to at least one.  We would need to see the wire mesh first, though.

BTW, if you are indeed using DoF, you may need to push your pixel sampling higher to avoid a granular effect in your background.

 

I am.  Thanks!  Recommended setting when using DoF?

BTW, recommendations for Shading Rate?  I thought I knew all my render settings, then read a lighting recommendation thread, and now I don't know what I know anymore.

 

I was using .1 for finals.  .2 for Medium-high.  Then I got confused when I saw a few using .2 for shading rate, but 10000 and higher for samples under Indirect Light!  Yowza that took a long time to render, even at low res.
