In the second part of this Unreal Tips & Tricks video tuorial, we take a look at Planar Reflections and Screen Space Reflections (SSR). Both of these provide more accurate ways of adding high-quality reflections to your scene than Scene Capture Actors that we looked at in part one, but at a cost.
Unlike cube-map-based reflections, Planar Reflections are distortion-free but come at great cost, since the entire scene is rendered twice on the GPU. SSR is a little less costly, but can only render reflections of objects that are currently on screen. We’ll look at how and when to use both.
