I mean, this is just a navmesh to begin with.

there's no need to install External files all you have to do is mount portal 2 and install the addon

all of what you see in this video is almost accurate to portal 2 retail itself https://www.youtube.com/watch?v=HJy7Qzf-1Pw

@Drago Yes Me and Lixue and femboy and Pop4484 are the current developers of this addon we started this off of an abandoned version of this addon Made by URAKOLOUY5 Our development is very slow but we are making gradual progress and added the viewmodel Bob from P2ASW and fixed Particle issues

Wait, are you the dev of the addon? Because this addon is mine and is navmeshed, feel free.
