Small build I used during testing. Shows flame jets over mature netherwart and from lava pools. Steam jets can occur over water blocks adjacent to hot blocks (in this case lava under the cauldron).

Fire Jets spawn over lava source blocks. They do not harm the player or any mobs. The height and duration is based on the number of lava source blocks beneath the fire jet.

Steam Jets will be generated around areas where lava meets water.

Testing some updates with Compitum Magia and came across this lava lake. It showcases steam jets, lava jets, and water splash particles from water falls. Not sure what that bat was thinking.
