Gap between Recast graph using RecastMeshObj

Hi,Aron.
I am working on npc Navigation. And I want my different npc can only walk in the designated area using Recast graph.At first, I try to use GraphUpdateScene, but i find it not performing well in the Recast graph.Then i find RecastNeshObj working with GraphUpdateScene really can divide an Recast graph into two area.But there is a problem that there always has a gap between two area,and i don’t know why.


And you can see a gap between purple area and the red area, I want them linked but are different area.

Hi

It looks like you have set the RecastMeshObj to Unwalkable Surface. Try setting it to WalkableSurfaceWithCustomID instead.

Sorry for so late to reply. I have tried to set CustomSurfaceArea,But it seems doesn’t work. And it will generate a surface on the Mesh. That’s not what i want.

Hi

Ah. I understand. The RecastMeshObj will not help you with this. You can however potentially use the NavmeshCut component with the ‘is-dual’ option enabled.
