    I have an Unity terrain where I painted several paths. I want these paths to have a different area cost than other parts of the terrain.

    How can I do this?

    If they are painted, you can't - you need Meshes because the NavMesh only cares about Meshes (and Colliders) and not about textures.
    You can create a Mesh along your path (or build it with cubes, they won't be visible in the game and won't collide with anything) and set the Surface Type to something like "easy to walk" instead of the usual "walkable" - then reduce the area cost. Bake. Done.
