This might be very basic, but I couldn't find something relevant to what I need (see below). I am working on a very basic thing: a 3D environment with some buildings, and actors walking inside it. It looks like following:

I mainly want to manage to have one actor standing around, idling, and another walking around the area. Right now, this is done through matinee + skeletal mesh groups, and forcing a looped animation on the actors:

But I realize this is super caveman-level. So I've build an AnimTree, linking the idling and directional animations to the corresponding nodes. But then, I'm stuck. I added the AnimTree in the actors properties, but nothing happens. I've tried MoveToActor, but no success - is there a thing to set to allow an actor to move? Also, I place the actors on the map manually (they are supposed to be unique), should I spawn them instead?

Every tutorial I find explains how to use an AnimTree for the player character, which is not what I want. I need a way to move the actors. I tried to look for AI tutorials, but only found UT3 bots-modifications, which is not what I need either.

Since I have so much trouble finding how to do this through Kismet, I'm starting to suspect this has to be done through scripting/coding, but I would like to be sure there is no way to do it through Kismet before going that route.

Every bit of answer about how to tell an actor something along the lines of "go in that direction as much as you can, then when you hit a wall turn 45° and continue" would be awesome.

I'll be happy to move/edit the question if there is any problem with it
