When creating a custom tunnel/cave layer for an example, you can change the variation in the floor or ceiling with a size for the noise and frequency/amplitude, What I want is essentially that i'd like to first add a layer of very big noise, and then a layer on top of smaller noise so that you not only have some parts of the ceiling that's 20 blocks above the floor, but also some that are 80 blocks above the floor, all whilst maintaining a constant amount of spikes from the ceiling. Additionally and optionally, it'd be cool if the variation of a noise could be masked with another noise... so essentially you could have a base noise that had like 50 height difference and 1600 scale, and then a 20 height difference noise on top with 100 scale, but masked with a noise in-between so there'd be varying differences in the ceiling height whilst also being patches of very sharp spikes from the ceiling... or "stalactites".
