I was able to use a combination of the cache glitch and the size glitch to get a giant biodome and multilevel platforms with stairs on the top of my freighter. This has completely transformed my freighter layout now.

Even though you cannot place a door on the biodome or power it, if you place, a short-range teleporter on an exterior platform where you are going to place the dome, then you can cache-glitch build a dome over the teleporter and then connect it to a teleporter outside of the dome from the outside. Both the dome, and the teleporter are still powered by the freighter as long as they rest on a Freighter platform.

It’s important to remember that you must place the teleporter first and exactly where you want it to be before you build the dome. If you move the teleporter, while you are inside the dome, you are stuck and have to restore to your last save. For the less experienced, I highly recommend doing this on a sandbox or Creative mode save. I also recommend that, while constructing, you save before you go into the dome each time. If not, you risk losing your progress if you end up getting stuck inside the dome and have to restore.

Now I have a teleporter just inside from the bridge of the freighter that takes me up inside the Biodome.

And for those who do not know, you can use the cache glitch to put your exocraft on your freighter as well. If you have any questions about how to do glitch building, check out Beeblebum’s YouTube channel.
