Referring to the docs, it is explained that the seek mesh can be retrieved by baking the navmesh and restoring the bytestream later. However, I don’t know exactly how to use it. Do I have to parse it again after saving it in json format?  
Examples are lacking. Can anyone help me?

Hi @taehoChoi and welcome to the forum

Once you get the byte stream with [RecastJSPlugin | Babylon.js Documentation](https://doc.babylonjs.com/typedoc/classes/babylon.recastjsplugin#getnavmeshdata)  
, it’s up to you to save and restore it. You can encode it using base64, upload it somewhere, copy and paste the encoded string,…  
And then, do the reverse and call [RecastJSPlugin | Babylon.js Documentation](https://doc.babylonjs.com/typedoc/classes/babylon.recastjsplugin#buildfromnavmeshdata)
