Missing vital SceneCaptureReflectActor for real-time planar reflections

It’s definitely something we want to support, but just haven’t gotten around to yet. The reason it’s had fairly low priority so far is that planar reflections tend to be so expensive (have to re-light and re-render the entire scene for 2x cost!) that they get cut in any decently sized level. But for small showcases the cost is acceptable and the visual benefit is huge as you noted.

Set a low res target, upsample with temporal AA, and couldn’t you run a separate set of shaders on the planar render targets? Output to 10-10-10-2 for HDR for example? A matched res render target would seem overkill for most uses of this anyway.
