    Hi,

    Having real problems seeing where I can define multiple navmeshes with a different radius. For example I have vehicles, small characters and large characters, so I need 3 navmeshes per scene I suppose?

    I use NavMesh.CalculatePath to generate the path because I prefer to move agents myself (they're all physics based and need that interaction at all times).

    But apparently there is only one navmesh baked into the scene? I must be stupid because I doubt Unity would be this short sighted, so any advice is welcome, thanks!

    I fear you are not stupid.

    The ability to only bake one mesh is a design flaw.

    Currently the approach to filter different sized agents would be to use the navigation layer / area / whatever they're calling it in 5 - system for segmenting where masked agents can navigate.

    While internally handled as such, it is not as powerful a pattern as straight up allowing multiple navmesh bakes in a scene. This should be on the way, but that obviously doesn't change things now. Layers should handle your present scenario though.

    Thanks guys, much appreciated. I'll be patient and wait for Unity in this case. Game is still a fair few months off.
