Pathfinding computes too small of a radius around points

Reproduction Steps

1. Create a path thats (seemingly) the only accessible way through an area outside of the navmesh detection.
2. when computing and during the debug you’ll see that the navmesh area that’s generated is in a straight line towards the goal
3. this will indirectly cause any potential path that is, logically, available to be marked as unavailable as it’s not within the given reach of the pre-computed navmesh of said path.

reproduction within the file:

  1. keep the pillar on the right and it will error
  2. move the pillar all the way to the left and it will compute (no error + navmesh path shown)

Expected Behavior

I expect the entire navmesh for terrain to be available during runtime as it makes it extremely difficult for AI to traverse large maps due to these limitations or to be given an furthest as possible path to move towards and compute from there.

Actual Behavior

The computation returns a NoPath not even providing a potential furthest point to compute again from in order to proceed to the next points, if possible at all.


the only work around possible is creating a custom pathfinding system which is not entirely worth investing time into if roblox’s functions properly on its own.

I don’t wish to bump the thread however I’d like to know if there’s anything more known about this?
