Reflective actors?

So, I’m working on a randomly generated horror game, so the entirety of my level geometry is created with actors, and I have puddles generated with the materials for the ground, and I’d like to make them reflective. I’ve literally no idea how to do this convincingly, as there’s no skybox and so far, it renders in reflections of stuff that aren’t even there, like these rogue lights and what not. Any way to increase the screen space reflections? or any way to make sure that the reflections work a little better? Or am I going to have to update into 4.12 and deal with the work of fixing everything up after the update?
