Does navmesn work in unity free? I can put a navmesh agent on a player. It looks like it works but it doesn’t say it anywhere I can find.
Nope. I’m unsure whether that is just the pathfinding or both. I’m assuming both.

This is really confusing because navmesh baking is allowed in the free version as of 4.2. I don’t know how much works, but I believe some. Some say it’s only good for static objects, and the pro is good for dynamic. I guess I’ll play around with it more when and if I figure out Mecanim. Thanks for the link, I didn’t see that.
I think Myhijims link is outdated information. In the license comparison it says navmeshes and agents are included with the free version: http://unity3d.com/unity/licenses
Off mesh links remain Pro only
My bad, sorry. Just thought the documentation would be up to date 
I am using Navigation in Unity 4.2 here:http://unity3d.com/unity/download/archive
I can’t say the same for all the other versions above it, but try it. I believe it has a mesh agent and you can bake your scene and static objects.
YouTube a tutorial. There are a ton out there I’m sure also you need to bake to make the navmeshagent move
