Just wondering what is the best approach to optimising a scene with many lights and different layers which don't use all the lights in the scene.
Currently in Maya (2018.4, seems I will be able to turn this off in 2019). render layers default behaviour seems to include all scene lights in a layer, so I am simply overriding the visibility of the lights I don't want in a layer. Is there a better way? Always seems that there is a performance hit when there are a lot of lights in the scene even so...obviously any render will be faster with fewer lights but just wondering how significant having unused lights in a scene is....
Thanks for any insight!
