This is going to be hard to explain because I'm not at my workstation today and I can't remember exactly what happened to cause this, but when I had a bunch of objects selected (some books on a set of bookshelves) and Render Selected chosen from the Render Mask dropdown, they rendered just fine in the VFB with everything else black but I also had a spherical vraylight directly in front of those objects which occluded them in the render. I.e. a circular black hole appeared in front of the objects like a cookie cutter. The light was set to Invisible and wasn't selected. So in other words the render mask was treating this light as an actual renderable object, and rendering it black.
I think this might be a bug. Either way, definitely unwelcome. I wasn't able to find a solution, so I ended up moving it out the way so I could render the objects properly, but this obviously changed the actual lighting in the scene, which wasn't ideal.
It's worth noting that when I selected the light with Render Selected chosen from the Render Mask dialog, it actually rendered the scene *through the light*, so I had a circle of stuff in the VFB where the light was. All very strange.
I could try to make an example render and scene soon if I get a minute.
