Nextbots - Using ladder navmesh

As the title says, I’ve been coding a simple zombie AI within the NextBot system, and I’d like them to climb ladders.

I’ve properly built the ladders into the navmesh, and it looks like this example: http://i41.tinypic.com/zxtqpc.jpg

My question is, how do I get the AI to use this navmesh? Is there any built-in functionality that I’m overlooking or are the ladders just something leftover from the other games on the engine? Help appreciated.

I don’t think this is possible in GMod

There might not be any built-in solution but applying animations and changing the pos yourself is entirely possible.

Yes, and the problem can also be that GMod may not support the ladder navmesh stuff ( And other CS specific stuff )

Alright, thought this was the case, good to have some confirmation, thanks :^)
