3d Point'n'click (ie. Sam and Max) pathfinding?

Blitz3D Forums/Blitz3D Programming/3d Point'n'click (ie. Sam and Max) pathfinding?

I've no idea how to even begin to implement similar pathfinding to that found in Telltale's Sam and Max episodic games. I'd like to. Complex pathfinding algorithms seem like overkill. Any ideas of how I might go about doing this? The simpler the solution, the better!
