The two lighting setups day and night have had all there components grouped to make life as simple as possible. The model is supplied with the daytime group visible.
In order to render the scene for night time, simply hide the group titled ‘Day –setup’ and unhide the group titled ‘Night-setup’ simple as that. Remember to reset your viewport to one of the appropriate night or day cameras though!
The particle system shower components are also grouped so if you don’t want the overhead of rendering an active shower simply hide the group titled ‘Shower-system’
The shower system has been set-up to work over the first 250 frames of the timeline.
