Floor reflection unity. I can t wrap my head around how do you make a floor that reflect the environment and just the floor. Here s a quick tutorial on how to create realtime reflections in unity 5. More info see in glossary window that are used for editing the size and probe origin properties directly within the scene. It is commonly used to create more subtle reflections such as on wet floor surfaces or in puddles.
From my understanding you create a material push the smoothness to 1 and then place a reflection probe in the scene and all the materials smooth enough. This approach is very hacky but you can use the new reflection probes in unity 5 to easily create realtime reflections for something like a reflective floor. There are two buttons at the top of the reflection probe inspector a unity window that displays information about the currently selected gameobject asset or project settings alowing you to inspect and edit the values. I suspect that this will be the hardest part of what you need to accomplish.
It may be possible to get some sort of sensors in the floor and then you re doing entirely custom things to read the data. I like this opencv asset for unity. Now i did realize that unity free has reflection probes. More likely you d use a camera in the ceiling and probably want to process it with opencv.
