you using the old reflection system from iclone 6 ...
Currently iclone 7 does not support screen space reflections so what you are trying to do is impossible,
the maximum you can do is enviroment reflections using IBL images and trying to bake your scenario for a mapping enviroment
trying to get as close as possible, but definitely this Does not work for flat surfaces.
It's one of the things I asked for more: "Do not launch iclone 7 without a screen based reflections system."
