I have the problem that the navmesh is slightly over the floor. so sometimes i can`not grip some small objects… how do i place the navmesh exactly on the floor?
You don’t need navmesh to grip objects. Nav Mesh is solely for navigation purposes.
i know but when i navigate with the nav mesh in vr it is over the floor and my hands cant reach meshes on the floor because the navmesh is over it and not on it…
I assume you presses the p key to see the nav data. This view always shows the nav data as bing above the actual floor. This is so its visible even when there are objects on the floor. If you look at the box extent of the nav mesh that is where the actual nav data is. That all said i dont believe your issue lies in the nav mesh.
You should check collision box of your floor mesh. The nav mesh uses it to know where you can navigate. Maybe slide it a bit under the reel floor level.
