Glass - IFSonly in DEcomb - MB3D with Parameter

some tipps/hints:
In IFSonly-Setups and with two heightmaps in DEcombination (one heightmapIFS in first and one in second DEcomb Part) u can get a solid/endless ground and so u can cutout - see example - parts of a typical amazingIFS setup and nevertheless the ground.

The smooth look is also a result of RoundedBox with rounded edges.

this "simple" setup renders comparatively fast - even with reflection (on my pc 8 minutes 3.820 x 2.880)

the "smoky" glas setup (for this formulas):
Absorbtion: 5
Refractive index: 1.2
Light scattering: 8
