When you set a big object on the floor it's no big deal, but as soon as the object is almost flat (ramp, transition...) it's nearly impossible to get something smooth without a flickering texture.
And even if you make it, from a big distance, those textures will melt anyway.
So the best best solution would be to be able to remove the floor square by square.
I know there is 99.9% chances of speeking to a wall, but let's bet on this 0.1%
