Definitely, From Dust is a big inspiration. Volcanoes and lava are the next planned feature after the atmosphere layer is implemented.
cool. I separated water from lava using a temperature buffer (water = 0 // lava > 0) which also added interaction between both types (freezing of lava by water). it was cheap. I don't remember if we told which channels we used here : https://www.gdcvault.com/play/1013667/Creating-a-High-Performance-Simulation
