It is possible to raise up the terrain under the floor very slightly, by editing the movie.mscope
Open the movie.mscope for your movie (maybe backup first?) in a text editor, and search for <constraints> which will be within a <terrain> section.
Either you can delete everything from <constraints> to </constraints>, and you will be able to raise and lower the terrain under the floor (to over the floor, if you choose).
Or you can change the height from -0.1 (10cm under the floor) to something else; if I put it to -0.01 then the terrain z-fights with the floor if I move the camera fairly high. This wouldnt be a problem if one was making the floor invisible.
