Hello, I'm trying to make an underground bunker as my starter structure using WordEdit .schem files. The problem I'm having, is that I'm spawning on top of the bunker instead of inside it...

I did use the //copy and //schematic save commands from within the bunker, and I do spawn inside of it when I don't use the Yoffset. but then then bunker is no longer underground...

Is this a design flaw on my part?

This has been fixed in version 3.1 of Starter Structure, with various new config options. With exact coordinates and offsets for both the player and the structure, it should be much more configurable. Thanks for opening the issue and giving the mod a try!

I've added (too many) new config options which will make the underground bunker idea work! Doing some testing right now, but with the following settings you'll spawn inside :) Will publish soon!

This is looking very promising!
