First time I am using UE4 and I am having a problem. We have created some roads with sidewalks where people are going to walk on the sidewalks. We created the static mesh in Blender and added collision boxes to the road component’s blueprint in UE4 to mark the difference between the road and the sidewalk. But when we add this road component to a level and encapsulate it in a NavMeshBoundsVolume we get some weird glitches. There comes gaps at random which our people can’t move past.
In the upper picture you can see the gap, and in the lower you see the component without seeing the navmesh (P). The gap comes at random, if I add the exact same component at another location in the same level, there is no gap, but adding another one might cause a gap to appear… The same thing happens when I add the same blueprint without the collision boxes, so just the static mesh made to a blueprint. So I suppose it does not have anything to do with the collision boxes in the blueprint.
Does anyone know why this is happening and how to fix it?
