So, I’m trying to write a voxel-based dungeon crawler, how would one go about generating voxels in godot?

Which kind of voxels? In which kind of view? FPS? Top down?
There is RPG-in-a-box, which is an editor made with Godot that lets you design games with voxels: http://www.rpginabox.com/
Otherwise I think you will need to code this yourself, most likely in C++ with a module. There is quite a lot of material to do voxel stuff in general on the internet, like this: Voxels – Page 2 – 0 FPS
I also did my own attempt here, though it’s still experimental: GitHub - Zylann/godot_voxel: Voxel module for Godot Engine

I made this node called a “cuber” whose “drop_cube()” method you call where you want to drop a cube. It requires the parent node to have a spatial node called “active_character”. You can then reference all the cubes you’ve dropped in the “cube” array. You’ll also need a cube.msh mesh.
Also it sounds like you want StaticBody, not RigidBody, and also you’ll want to snap the character’s position to a grid. This is a hackish way of making voxels.
extends Node
var cube_drop_dist=5
var cubes=Array()
var max_cubes=500
var max_cube_rate=3
var last_cube_time=0
func _ready():
pass
func drop_cube():
if OS.get_ticks_msec()>1000/max_cube_rate+last_cube_time:
if cubes.size()>max_cubes:
cubes.back().free()
cubes.pop_back()
force_drop_cube()
last_cube_time=OS.get_ticks_msec()
func force_drop_cube():
var cubedrop=RigidBody.new()
var active_character=get_parent().active_character
cubedrop.set_translation(active_character.get_translation()-cube_drop_dist*active_character.get_transform().basis[2])
var cubemeshinstance=MeshInstance.new()
var cubemesh=load('res://cube.msh')
cubemeshinstance.set_mesh(cubemesh)
cubedrop.add_child(cubemeshinstance)
var collshape=BoxShape.new()
collshape.set_extents(Vector3(1,1,1))
cubedrop.add_shape(collshape)
cubes.push_front(cubedrop)
add_child(cubes[0])
func delete_cubes():
for i in range(cubes.size()):
print("cubes.size()=",cubes.size()," i=",i)
cubes[i].free()
cubes=Array()
