Artificial Biome not Working

[diekaki93]

Hello Players :)

Sorry if this was discussed before but i did'nt find any help on this topic.
At the Moment i'm trying to build a stack of artificial Biomes. The requirement of 16x16x16 blocks is more than fulfilled because i made a whole claim 64x64x16 big Artificial Biome. Now the Problem is, that creatures and Treasure chests spawn on Top of the artificial biome's roof o.O

Material used is mostly Igneous Rock and Hardenend Lava, The Walls are made of Stone outside the claim but surrounding the whole platform without any gaps. the roof is made from Stalactite because that should be the second artificial biome.

Maybe i'm missing details. -_-
Thanks in advance :)

Seems perfectly normal. Warmworms and Miru do spawn on stalactite/siltstone at night. Are any of the platforms not producing spawns at all? If so, the height of the platform may be the issue. I place my spawning spots as close to the bottom of a chunk as possible. You can have more than one in a chunk, but mainly compatible biomes such as lava/corruption for example.

Chunk alignment matters on the vertical as well, can't tell why you're getting all the spawns on the roof there though - the easiest solution is probably to make the roof out of crafted blocks to prevent them spawning above.

I used to make large spawners in the past with glass slabs' ceilings way up at the top of the sky, it's quite a chore but quite rewarding for the see-through result:

Some spawners can indeed be mixed in the same chunk (say, Dried Leafis, Trogs and DustEvils can all spawn in the same chunk) but lava and corruption are definitely not compatible - namely, enough lava-related blocks wil disable all corrupted spawns.

@Deadpool
Yeah on the Lava Platform aren't any spawns at all -_-
And the Stalactite layer doesn't even have a roof.

@entuland
Thanks for your Spawner guide :)
Is it necessary to seperate those chunks?
I've come to the conclusion that it might be easier to craft 955 excavators to hollow out a whole claim (Calculation done with 64x64x16 blocks and 5 layers) and just add some floors at the right hight. Multispawner made that way could be a cool thing.

You're welcome!

The advantage of doing large spawners over the ocean as I show in the guide is that you get less "noise" from nearby chunks spawning other mobs - it's definitely faster to fill a blueprint with burst fill than digging large areas.

One claim may not even be enough depending on what you want to achieve, some of those spawners are 3x3 claims.

Some spawners can be mixed up as mentioned above but the vertical is kinda "dangerous" if you want to blueprint the spawner and repro it somewhere else, that's why I made my all-mobs-spawner with 15 free blocks between the floors to ensure they fall into different chunks on the vertical:

Well i need material anyways so it won't be wasted time to dig until i reach the end of the world :D
But still i wonder why there's no spawning at all on the lava platform.
It's got a roof, no artificial lights, floating over the ocean, 16 blocks high walls, 64x64 only lava and Igneous Rock and so on. is there a possibility to check in which vertical chunk i am? Guess by calculating using the xyz position?

The link I provided above gives info about how to find the chunk boundaries:

You _are_ getting spawns, only that you're getting them on the roof - as mentioned earlier, I can't tell why it's spawning only on the roof, you may be hitting a bug if the lower floor is too close to the water though.

Make sure there are at least two or three free spaces between the water surface and the floor and replace the ceiling with crafted blocks, that should force the spawns inside the closed room.

In order to troubleshoot that specific installation better I'd need to see it first hand.
