@beanzvision, unfortunately checking "render instance" may visibly "color" the instance in the viewport, but it makes to not render the light instances at all.
also: putting a corona light in a mograph cloner (without checking render instance) does also not work, as above, with correct color. See attachment (from left to right: cloner with original light-instance-original light)
also: importing a corona light, or light fixture with included corona light, from the content browser resets the light color in that corona light.
Needless to say that this is a serious issue and that this functionality (instancing or cloning lights) is imperative for an organized workflow!
I really hope this is at the TOP of the list with the developers at this moment and a hotfix for this is eminent!
I don't understand....This functionality worked properly in many beta versions, and now that I was forced to switch to the paid/commercial version (because ranchcomputing render farm upgraded to commercial version and I depend on them for every project), it stopped working.
:-(
thank you in advance for making this a priority, since there is no workaround...
