hi,
I have a habitude to organize all my decorative objects and furnitures in an invisible null called 'symbols'. Then I make render instances and place them in the scene.
However when the 'render instance' option is enabled for the instance, the original reference object is also rendered in IR (not final render), even when parent is set to invisible for rendering.
I am including a quick test scene to see if you can reproduce the error:
1) start IR as is on startup file, it renders only the instance as expected since the render instance is disabled.
2) enable the render instance in the object manager
3) restart IR and both the render instance and reference object are also rendering now, while this is not expected behaviour since the parent is set to invisible.
We have had this problem on R18 and R19 since v5,v6 and 6.1, and tested with same results in R23 v7 too
my workaround is to lower my symbols null to height -5000, but it needs to restart the IR to see it dissapear. With parsing times often around 6 minutes, it's quite a pain to see p.e. a reference tree in the middle of the livingroom...
cheers, koen
