Doom Level Flowcharts?

[VanaheimRanger]

A year or so ago I remember seeing a webpage someone had made with in depth flowcharts that he had made for all the original IWAD maps of Doom.  It was really cool and would be useful for map designers.  But ofc now that I need it, I can't find it anywhere.  Does anyone happen to remember seeing this as well?

It isn't as helpful as I thought it would be, but is still very interesting :)

Lol, yea, I had asked on a discord channel earlier and Peg beat you to it.  After actually looking closer at the downloadable pdf there, these might be more useful than my previous post implied.

 

Gonna keep these for reference :)
