@TomG_4MB (TomG_4MB) posted a new topic, subject "NavMesh Not working with Subtractive BSP". It read:

   hi guys,
    
    My NavMesh is not connecting when I have set up a building using a Box BSP and used Subtractive Box's to create doorways. I have set up buildings like this before so not sure what has happened, I am now using 4.5.
    
    Any ideas?

Then @Rudy_Q (Rudy Q) said

    Hello obitomkenobi,
    
    After looking into your issue I was able to find a report on this in our bug tracking system. This is a known issue in 4.5 (UE-4442) and the development team are looking into it.Thank you for the information that you have provided I am sure it will help us narrow down the issue further.
    
    Cheers

    Hey mate, 99% sure this was fixed in later versions of UE4. What version are you using now? Definitely not seeing it in 4.8

    Hello keyle,
    
    This has been fixed in a later version of the engine. I have provided a link to the commit in case you are working from source and would like to integrate this solution into the engine version that you are using.
