Decided to learn how to use Blueprints by making some quick fixture props, and giving them aesthetically pleasing but optimized lighting setups - that would allow good, consistent object-based lighting, with some controls to make it easier to illuminate larger spaces with fewer sources.
I posted WIP updates for these here: https://polycount.com/discussion/190402/ue4-learning-lighting-art#latest
Most of these Blueprints use Stationary Key Lights, with a supporting Static Fill Light with an attenuation value that can be multiplied when the Blueprint is placed (these are made to work with Static/Mixed Lighting). Common Controls/Variables also include a basic On/Off, Brightness, Colour, and Shadow Casting.
