I just sent in a ER request to be able to configure lights and the settings of such individually for each configuration of assemblies. As of now the only way I know of is to create separate assembly files.
This is very important when a specfic camera requires specifc lights and from other angles the lights are not ideal. So if I am to set the settings once and keep them or even schedule a render overnight with different cameras and different lights then I need to set them up with a complete new assembly file for each camera angle.
Any other suggestions?
