Another fun Substance Designer sketch. Trying to get the best ice shader I can without using refraction.

Some glacier caves are formed by geothermal heat from volcanic vents or hot springs beneath the ice. An extreme example is the Kverkfjöll glacier cave in the Vatnajökull glacier in Iceland, measured in the 1980s at 2.8 kilometers (1.7 mi) long with a vertical range of 525 meters (1,722 ft). *Neat!*
