Troubles with recastgraph holes

[Anvi]

I’m getting different behavior from objects that to me seem to be different. Using version 4.2.19

The desired behavior is, that the navmeshcut would follow the object.

I have

1. Forklift
2. Pallet
3. Working cell

• All have NavmeshCut component on their parent.
• 1 and 2 have a non-kinematic rigidbody.
• All have a non-trigger collider.
• Pathfinder has a recast graph with LayerMask = Everything.
• When I move 2 or 3, the navmesh hole follows the object.
• When I move 1 (the forklift), the navmesh hole seems to follow the object BUT the initial hole stays in the forklift’s original place. (see video)

If I manually re-scan the graph from the PathFinder, the hole moves back under the forklift.

I can’t figure out why the forklift is different?

It’s because your forklift is included in the layer mask for the recast graph, and it has a collider/mesh that causes a hole to be baked into the navmesh.
I’d recommend putting it in a layer such that it becomes excluded from the recast graph’s initial scan.

Thanks!
I think I tried that already… Just to be sure we are talking about the same thing:

• The forklift and it’s children are on Layer “Vehicle”
• That same layer is excluded from the recast graph’s LayerMask
  With these, the result is the same: the forklift leaves a hole to it’s initial position.

Hi

It looks like you are also including all Untagged objects in your scan.

Yes, that was it thanks!
For future reference: I had (maybe an accidental click) added a Tag Mask “Untagged”.
