How can I make my imported level model collidable?

Questions & Answers
1

So this is probably going to sound horrible, but I've imported a mesh from blender that I'll be using as my level's map, and I don't know how to apply physics to it. In the sense that I don't want my player to be able to fall through it, I need to make it solid. Again I'm sure this is a noob question and it's easy to do, but any ideas?

You should attach a mesh collider to your object.

Another alternative (that automates the above process) is to write a postprocessor script.

Here's an example that place a meshcollider on any model that contains "level" in its name, and for any child models of it.

You'd make a js script file called "ColliderOnLevel" and place it in a folder called "Editor"

class ColliderOnLevel extends AssetPostprocessor {
    function OnPostprocessModel (g : GameObject) {
        if (g.name.ToLower().Contains("level"))
            AddMeshCollider(g.transform);
    }

    function AddMeshCollider (transform : Transform) {
        transform.gameObject.AddComponent(MeshCollider);        
        for (var child in transform)
            AddMeshCollider(child);
    }
}
