[4-26] Landscape Navigation Mesh bug


I place a large navigation mesh on the landscape I created. However, the navigation mesh does not work in some areas on the landscape. I’ve tried this several times by creating different maps, but no navigation mesh is generating in certain areas on the landscape.

But I don’t think the problem is caused by navigation mesh. When I throw other models to those areas, navigation mesh is created.

Anyone have any suggestions for a solution?
