The stones look like a rough mountainside!


@Germanunkol
I think the reason why the carpet looks like it is hovering is in the Stone surface:
Our eye recognizes a rough surface and a total flat carpet above, thus the brain concludes the carpet has to be at least as high as the highest stone part the eye sees, otherwise the stone had to pass the carpet which is not the case.

I think that'll be not so bad when the heightmap is more realistic.
