A few days ago I searched for a tutorial for making reflecting floors, but everything I've found was way too laborious. So I started searching for an easier way and I indeed found something. I'm going to try this out and make a tutorial when I've found out all features and how to use them to get the best result. The whole thing needs only 3-5 steps. I already found a way to make the whole floor more blurred for a more realistic effect, but it's still a little bit buggy. I'm working on it.
