it would be useful to have the option to see the render elements while using the interactive render
Elements like the reflect can say a lot and i use it to make the material changes often
I guess this would be possible as alpha is visible in IR. You can also temporarily disable diffuse(/other) component of a material to see reflections only.
A pretty neat idea! Just the other day I was checking to see if there are render elements in the IR… 
this would indeed be usefull. we have to setup alot of masks on certain sets. it’d be nice to see them popping in in realtime.
