In Unity, I'm trying to get the raycast to hit the navmesh only, but I cannot find an option to place navmesh on a specific layer.

Is there a way to raycast to the navmesh itself?

  • \$\begingroup\$ Can you explain what you're trying to accomplish? The navmesh is not a physics object visible to raycasts, but we might be able to implement the feature you have in mind in a different way. \$\endgroup\$ Commented Apr 27, 2021 at 20:56

  • \$\begingroup\$ You can fire a "navigation ray" along the navmesh to see if it hits a boundary, or find the closest point on the navmesh, or the nearest edge from a point on the navmesh - are any of those what you're looking for? For the benefit of future users, I'd like to get this question to a place where we can post a more useful answer than "no". \$\endgroup\$ Commented Apr 27, 2021 at 21:21
  • \$\begingroup\$ NavMesh.Raycast() sounds like what you want. Have you tried that yet? \$\endgroup\$ Commented Apr 27, 2021 at 21:53
  • \$\begingroup\$ Yeah, I looked into navmesh Raycast. The objective is to sample the navmesh without a ray terminating against things like walls. The Nav ray mentioned above would still suffer from the limitations expressed in the post, unless I am misunderstanding it's function. \$\endgroup\$ Commented Apr 27, 2021 at 21:55
