Asking what nodebuilders were used on different (large and complex) maps.

[Grassy chunks]

I really want to know what nodebuilder the map 13 from requiem (town of the dead) used. 

As this map is from 1997 before doom source code was released, before boom etc. (really liked the 3d bridges for vanilla) 

 

Also what nodebuilder were used on okuplok,deus vult and sunder mapset. 

 

Looked all over the internet trynna find an answer for this question and found no success. 

 

Also what's your preferred nodebuilder for maps where there are vertices, linedef and sidedef over 50000.

 

I use the zennode nodebuilder myself and sometimes experiment with zdbsp, zokumBSP etc.
