I'm sure I've used ths millions of times, but most recently render selected is not working as expected....
if I drag in an object from within a nested stack - for instance if i drag in 'label2' (see screengrab attached), then it just outputs a black render.
If i drag in the 'Bottle' group however, then it works just fine.
Just started happening recently - but not sure what changed.
