for example adding viscousity to lava so it slows down as it cools down, and when its drippng from a height the lava acts like honey but its still flowing and when it cools down it hardens in place.
is it possible or is it too performance intensive????
gel is already viscous ish so you can probably add the same code to lava
Viscosity is a state between solid and liquid, so it's very close to the concept of moving solids (at least it has similar math to it, like force), and moving solids are one of the already discussed suggestions that won't get added. Adding new properties like viscosity is also rare and probably won't happen. Also, changing behaviour of lava like that will definitely break a lot of saves.
Gel is not really viscous, it's sticky, and that won't fit to lava. Also again, that will break a lot of saves.
ah ok, i get it
