Lava Flow Material
In this lava material I was specifically trying to represent large, overlapping viscous forms of flowing lava. Getting the liquid-looking, sludge-y base forms was the biggest challenge at the beginning, and then getting the emissive lava portions to look good and blend naturally with the rock portions was the part that eluded me the longest.
Another material I made a while ago and am just now posting, I'm pretty happy with how this turned out, I think this was a piece that indicated a step up in my material-crafting ability.

Lava variations the substance is capable of producing, including the unusual blue lava.
Albedo + Emissive combine to create the base colors

Exposed controls for the Lava substance. Fairly basic and straightforward, focused mostly on being able to change the major shapes.
