Testing limits of Underground Rooms

[TOKEN]

I have dug out a 23x23x3 block room at the bedrock level, which doesn't seem to be a problem for the game mechanics. The ceiling is unsupported by any center pillars. The only thing supporting this ceiling is 50+ layers of stone blocks above it, which doesn't seem to bear down with any weight.

After enlarging this room to 27x27x3 blocks, i broke out a ceiling block and the ceiling began to collapse.

try to build a room of the same dimension over it, if it work, dig the floor of this other room and replace the stone, after retry to walk on it..., but i think the problem come more when you build a building outside of the ground...

from the floor you are now, you can build 248 other floor to have the maximum you can build, with this one it's make 249, after this, at 250 it's not working, the block don't rest in place...

Yup like I said in the 7dtd forum. I believe this will undermine the strength of buildings above. Ive had my bridge fortress start falling apart because someone was mining under the ground. I'm quite sure if your down deep enough you could build some massive caverns. with no worries. Have to try it :)

Here is a screen of the room after ceiling collapse has stopped.

that could be a good way to mine.

Not really, all the blocks that fell out of the ceiling were destroyed.

Yeah, collapsing structures and destroying containers just looses materials/items. fun to watch, but a very big waste of materials. Hopefully they fix that. Seems silly when one blasts a hill to rubble and the collapse only produces a small number of blocks based on the initial blocks broken by the blasts and none of the collapsed materials.

I built this test structure directly above my collapsed room, the tower and base are completely solid concrete and it extends to the highest buildable point in the world. I had no problem getting the metal ladders to stick to the side of the tower, so it does not seem like my very deep undergound construction has weakened the integrity above ground. The gap between the bedrock and new ceiling is at least 15 blocks, so thats a pretty big gap.

Try building sideways out from your tower. The structural integrity is not going to be well tested simply by going vertical. Concrete can normally be built horizontally 6 blocks. With your huge underground room it would be interesting to see if you would be able to build outward to 6 blocks or not.

Another good test would be to build concrete stairs circling around the outside of the main tower. I have noticed that when structural integrity is weakened staircases often stop sticking to the walls.

I really like what you are doing. These are the types of "stress tests" more of us should be doing for the devs during the alpha phase. I wish they would give us players a list of things to try to test the engine they have created and find places that need to be fixed

There's a problem with larger structures (and perhaps concrete/reinforced concrete) and the stability calculations. I've had many occasions where I attach a single block to the side of another (and the existing block is well anchored), and the new one simply falls off.

I placed a sleeping bag in the center of my underground room and used the respawn marker to verify that I was directly above it. So this 2nd structure is more directly centered above the room.

I was only able to build on 2 concrete blocks or 4 reinforced concrete blocks to the side. A stone stair added to the side would not support my weight. So this provides a clear example where the structural integrity has been weakend.

+1 I have found this to be the case.You can get away with some stuff but not everything.

On my original structure I was able to build stone stairs around the tower and build out a concrete beam to 6 blocks length. I guess this one is not directly above the the undergound gap.
