Right, Let me clarify some things about this trick. It is vanilla/boom compatible. You have to use the ZDBSP (0 reject) nodebuilder. It is buggy during construction but once it's there the user shouldn't notice anything. You shouldn't overlap midtextures like in the demo since different ports tend to render it differently. You can overlap triggers like this as long as they don't touch any sector edges. There are some exceptions to all these guidelines.
Here's an example of how to make a basic multiline with ultimate/gzdoom builder. make sure the lines are all of the same sector by joining them with ctrl+j. Then just ctrl+x the vertices. You can download the demo wad here:

It's Vanilla compatible, but you should try running it with a few ports to see the rendering differences.
