I’ve just comared the element demo 4.11 and 4.15:
4.15:
4.11 :
While I think the lava could be faked to a very bright lava (because even this type of lava exists) I still prefer the “cooler” lava of 4.11. If your goal would be dark orange lava you just failed your job in 4.15. And that said there is not only bright white lava but even deep orange lava like in 4.11 and almost pure red lava as well. While this was possible whit ease < 4.15 it seems you can only get very very hot and bright lava in 4.15 now. And everything that is not lava (neon signs, lasers, magic bolts, …) is doomed. I think this is a step backward and not forwards. It’s not more realistic but forced and limited realistic and less unreal …
