create a navmesh from a blender export

Hi all,

I’m quite new to blender and panda3d.
Can you guys please guide me how to create a navigation mesh from a Blender model?

Right now I’m dealing with the problem of creating the mesh inside blender.

In the documentation, the explanation on how to convert from 3DS MAX is pretty elaborate, but I couldn’t figure out how to create meshes inside a Blender model.

Thanks in advance!
