how to remove noise gradient in zylann's voxel plugin?

Godot Version

4.2

Question

i’ve been trying to use zylann’s voxel plugin to make some procedural caves recently, but ive run into an issue. theres a gradient on the noise that makes the density change depending on height, which is very irritating and isnt something i can seem to get around easily. how could i remove this gradient? i cant seem to access the script of the voxel generator at all. im still trying to get used to godot, so perhaps im just missing something, but i cant figure out what. does anyone know how to solve this issue? thanks in advance! :>
