I have read some threads from years ago about people having trouble controlling the lighting of a linked file from within the host file. I haven't seen any solutions to this issue and was wondering if there is one.
I have had success setting up a perspective view in the linked file and turning on/off the fixtures I want to render and then, in the host file, I choose to override the settings of the linked file by choosing "From Linked View" in the Visibility/Graphics dialogue and selecting that perspective view I created in the Linked file. I don't know if this is the correct way to do it or not. Also, I'd like to know if I can edit this from the Host file or if I just have to close the Host, open the Linked, and modify the settings in the perspective view.
Depending on which settings you are looking to control, you may be able to control it from the Visibility Graphics in the Host file, but if you are looking to control visibility of individual elements, that would need to be done through the linked file.
