Blackfrost Coal Works (skybox fit)

Another build made for ocean biome.
Again, two blueprints - one for the entrance (optional) and one for the dungeon skybox.

Although it was build for early game (Bronze era) and was built in burial chambers, i highly recommend to use mountain cave skybox because it's entrance is always at the edge of skybox which makes everything easier. Out of 30 burial chambers i spawned, this build could fit only in a single one. Burial chambers have really cool environment, but the random location of it's entrance makes it difficult to work with.

The dungeon was made as a puzzle so i don't recommend adding enemies inside. The outside part (Entrance blueprint) has several skeleton spawners.

About the dungeon:
Blackfrost Coal Works is an abandoned penal colony carved into an island, where dverger convicts once mined coal from shafts that plunge deep into ancient permafrost. The gates stand open, the mines intact and silent, as if the entire colony simply walked away. Skeletons tried to get inside but with no brains they couldn't go further from the entrance. Can you do it?

The dungeon consists of several separate floors and the player has to solve the puzzle or find the secret word to move to the next floor.
There are also hidden items to be found in some of them. Have fun solving puzzles and searching for hidden items.


Step-by-step Instructions:

1. Find a place in the ocean where you want to put it and find the right altitude. Right altitude for an artificial island (entrance) would be at 30-32 meters. That is the last number in your POS coordinates (X,Y,Z)

2. Use the command to spawn frost cave in front of your character:
Spawn_location MountainCave02 pos=0,0,0  - this will spawn mountain cave in front of your character and raise the ground to that point.

3. Now that we have a cave entrance we can work with, let's remove excess of materials around the cave (rocks, stalagmites, stalactites, etc). The command is:
object id=*rock* radius=50 remove  - this will remove everything containing word *rock* in it's name in 50 meters radius. Luckily, everything added around the mountain cave entrance has*rock* in it's name and running this command will leave the entrance as the only instance there.

4. Place the Prison Entrance v4 blueprint. Select the blueprint and try to aim at the front bottom part of the cave entrance to cover everything left of the frost cave entrance (making blueprints more opaque in Planbuild settings might help here). This is a bit tricky and might require several attempts. Don't forget you can use BP.UNDO to undo the placement of a blueprint if you didn't get it right.

5. Now that the entrance is done, let's move inside. Enter the dungeon and remove everything inside using PlanBuild removal tool. Don't worry, the white box for the entrance cannot be removed this way. Hold Alt and click to remove bigger area at once.

6. When everything is cleared, place the Blackfrost Coal Works v3 blueprint aiming at the bottom of the white box.

7. (optional) If you want to rename it and make it show Deep Ocean Cave when you enter instead of Frost Cave, aim at the white box and type this command:
object f=Teleport,enterText,"Blackfrost Coal Works"
IMPORTANT: place both blueprints with infinite health to prevent obtaining late game materials early.

This build is vanilla friendly.
