navigation distorted on stairway

Hi Forum,

I have a problem with the Navigation for my AI NPCs which drives me insane. On a stairway inside a building the navigation is somehow distorted, so that the AI Characters can’t get to the next level. The player (FPS game) can climb the stairway without any problem. Here is what I already tried without success:

  • made a custom collision ucx for the stairway - no effekt, changed again to “complex collision as simple” - no effect
  • changed the step height and maximum slope in the navigation project settings
  • played around with all the others navigation projekt settings, which I honestly don’t really understand

Any help or hints much apprechiated.
thanks a lot
